The Robert Koch Institute (RKI) – in its capacity as the central federal institution for public health and as the German national public health institute – publishes the Corona-Warn-App on behalf of the German government. The app serves as a digital complement to distancing, hygiene and wearing masks. It uses Bluetooth technology and the Google Exposure Notification APIs. The app is designed to help break infection chains by informing you if you were recently close to someone who subsequently tested positive for corona. However, at no time does it collect any personal information. Who you are and where you are remain secret – and your privacy is well-protected.


Exposure logging is the core of the app and should always be active. When enabled, smartphones exchange encrypted random IDs with other devices using Bluetooth. 

The random IDs only provide information about the duration and distance of an encounter. No one is able to identify the person behind these IDs. The Corona-Warn-App does not collect any information about the location of the encounter or that of its users.

Based on maximum corona incubation times, the random IDs your smartphone collects are stored in an exposure log for 14 days and then deleted. If a person is diagnosed with corona and chooses to share his/her own smartphone’s random IDs, all persons previously encountered will then be notified anonymously.

No one will know when, where or with whom the exposure event took place. The infected person remains anonymous.
In addition to the exposure notifications, affected users will receive clear recommendations for action. Important: Information about the notified persons is not accessible at any time.


The Corona-Warn-App is designed to be your daily companion, without knowing your identity. This is why the app cannot tell anyone who you are. Data protection is fully guaranteed throughout the app’s entire service life.

• No registration required: No email address and no name need to be submitted.

• No personal information is transmitted: When you encounter another person using the app, your smartphones only exchange random IDs. They measure the time and distance of an encounter, but do not allow to identify persons or find out locations.

• Decentralized storage: Data is stored only on the smartphone itself and deleted after 14 days.

• No third-party access: Neither the person reporting a proven corona infection, nor those who have been notified can be traced – not by the German government, the Robert Koch Institute, any other user, nor by Google.

This app is not intended for any use outside of Germany. Corona-Warn-App is the main corona app for Germany, where it is interconnected with the national health care system. Despite of the above, Corona-Warn-App is also available in this country. It is provided for anyone living, working, vacationing, or visiting Germany regularly or for an extended period of time.

The terms of use for the Corona-Warn-App apply: By installing and using this app, you accept these terms of use.

    Very useful and protects our privacy. Perfectly shows the advantages of open source and our democracy to respect your privacy rights! The functionality will be greatly improved in the following months and everyone should download it. It is better to have an app with limited capabilities instead of a great app function wise which doesn't respect your privacy!

    This apps does exactly what it is supposed to: warn you if you've been exposed to people that later tested positive. And it does it without ever requiring any input from the user, silently in the background. Moreover, when literally every large corporation collects all possible personal data and telemetry, this app does none of it and operates in a very clever way. It is even open source! 5 out of 5, no doubts.

  3. Eva Kapoun-avatar

    The concept is probably good however the execution is very poor. There is no detail info where or what time I met an infected person. So the app is just showing useless information. I meet a lot of people through my job and of course the app goes red time to time. I have been tested 3 times negative after a red warning but I never been able to upload QR codes. There is always an error message saying QR code not valid.

  4. Simon Bone-avatar

    The app ignores your time settings if the language is set to English. It displays the time only in 12-hour/AM/PM format even if the phone is set to 24-hour. That's annoying.

  5. Edward Turner-avatar

    Edward Turner


    Absolutely useless. Now the app has a contact journal function where I have to manually input data! why doesn't this ridiculous country allow the warn app to track my movements? Then i don't have to enter anything. Then the data can be properly analysed. Germany has demonstrated it's incompetence on a global stage. Embarrassing, but what can expect from a company like SAP?

    Great App! Respects DSGVO AND can save lifes! I was warned and went to the test centre. QR code scaning worked perfectly. Same for many people I know.

  7. Stefan-avatar



    Great app. Would be nice to see which regulations and contact policies are in place for different states. It's a mess currently and this app should unify this information.

    Never got my test result until it showed as being expired, your statistics are pretty much meaningless and how am I supposed to check for different incident counts in different cities when I'm going out of town... Not making this app pretty much mandatory for going into overfilled grocery stores makes it almost useless anyways. Try harder on improving these basic flaws, give more settings to decide on/with and more people will hopefully get a reason to download at some point

    App does not work. My daughter tested positive for corona, she only had one try to enter it into the app and it didn't work. She wrote them and they updated the status. We live with her but never once did we get a notification that we were at risk. My sister's husband tested positive and she also never got a risk notification even though they were right the whole time, and their cell phones were right next to each other for several days. Bogus! Thanks for wasting out tax money!

    Worst app ever for tracking Corona. Didn't worked at all. I was in quarantine because my roommate got infected. So I was not allowed to go outside for testing. They send a team of doctors with the car and then they tested at home. They told me I can scan the QR Code and within one day I would get the result on the App. This was three weeks ago and I still didn't get any result. The status on my app remained on green as well although the status of my infected roomate was on red.

    The app did not update automatically! The available update was not listed in the Play Store list of upgradeable apps. I just noticed it because some of the new features where missing. I don't know if this is an app or an android / play store problem, but I did not notice any other apps that did not update.

    Secure, up to date, and discreet. The new update provides a summary of the new incidence numbers and a journal to manage contacts, both of which are quite useful. The journal being locally stored on the phone is a particularly important feature, as I would not like to share this data.

    It makes my Bluetooth devices not working with the phone, so uninstalled. I UN-pair all my Bluetooth devices, reboot the phone, pair them again, as directed. It works for a couple of days, then it doesn't work again. Uninstalling it again until you really solve this. :(

    Doesn't work. Got tested positive. I have recovered totally now but the app still says I should a expect a phone call form authorities. This procedure is long done but the app is still stuck at this pount and not showing my exposure anymore. Update: worked. But still the battery is an issue. 4 stars after the update. Thank you.

    Few days ago the error "Expose check failed" appeared. Reset of the app helped, but lasted only one day. Error is back... Took month to fix it. Fixing those bugs should be done faster...

    It should provide visual stats for users, real-time updated figures based on location, and graphs, instead, it provides zero info. It is more of a tracker with no practical use. For an important pandemic related app that is suggested by the state, it deliver not even minimum of what it should.

    When I was installing it for the first time, my only concern was battery drain. After couple of months of usage, I have to say it's very nice app, easy to use, also no excessive battery usage.

    As the only authorised tracing app in the country, this app has a responsibility to be an authoritative source of information. The RKI are the authoritative source on e.g. local incidence rates. However, the app provides next to no relevant information. I haven't seen a contact for months, and I wonder if anyone else still actively uses this.

    Es nehmt Informationen mehr als notwendig. Bluetooth und Standort immer ein .... battery läuft zu schnell. I have deleted the app and then reinstall it but i can't register the QR code bec. I have registered it before ... so i cant get the result ... so useless

    You have to exclude the app from battery optimizations to be really sure it works. Could be tricky for older people... Other than that works!

    I can trust that it works, unlike the stupid danish smittestop app, and i can use it here regardless. Sadly not many danes use corona apps. I like the journl.the german corona statistics are not very relavent for me. Would like to be able to query my region there. I once did a corona test in germany which i scanned but not display result. Please add feature: My phone is old so once every few months i need to reset my phone so i would like to be able to export and import my collected corona ids.

    First of all, it says using this app is voluntay. Well it is not actually! It is the only way you can be informed about your Corona test when you visit your Hausarzt (Family-Doctor). They won't inform you about the results per post/ tel. So you "Have to" choose this way even if you are not happy using this app. Secondly, all over the app intro, they explained it is your choice whether you want to share your results with others or not. However, before QR-Code scanning, you must ACCEPT sharing!

    Easy to setup definitely a "no brainer". Curious to see whether it loggs a Corona case... The other side how many life's could have been safed probably if this app would not have to run under GDPR? A pity that political correctness does not allow this discussion and so we are choking the technical possibilities which such an app could have.

    Love the concept and hope it works as intended. Sadly i got tested a couple of days ago and the result in the app is still "unavailable". I checked with the lab - it was negative. But the result on the app should arrive too. Are you aware of this? Whose fault was this? Where can I report this to with more detail so that fixes can be made?

    I appreciate the app and it's help but I find it grossly misleading that it says "No exposure up to now" and gives you a green status based on the app's data only without disclaimers about "offline" infections. A lot of people will take it for a fact and go off the app's status and data only and forget that it can be inconclusive. In my humble opinion, there should be a disclaimer on every status along the lines of "No exposure that we know of" / "No exposure caught in our radar"

  35. Aziz Demirezen-avatar

    There are comments here, stating that the app doesn't really work: People report themselves positive, but even their partners don't get notified... Why is the number of all encounters not shown, on a daily basis or at least in total for the last 14 days? Is it also against the privacy rules? It would demonstrate the functionality of the app. Without such info being shown on the main page, I've very little confidence that this app is being tested properly and consider deinstalling.

  36. Dan-Timon Rudolph-avatar

    Can't read the QR code on the test. Problem is not the code itself, because it can be read by my phone camera. It's just the app that shows the camera view but never identifies the QR code.

  37. Michael Merten-avatar

    Michael Merten


    In order to share data with the RKI, a unique identifier must be sent to Google. With all the money involved in running this app, why must anything still be shared wit Google?

  38. Sener Kocyigit-avatar

    Sener Kocyigit


    1-If you get the QR code via SMS, you have a snapshot in your phone, not a piece of paper, so you cannot scan it and there is no option to select a snapshot from gallery!? 2-The code in the message has 20 digits, app allows you to enter a 10 digit code! So if you are diagnosed & stressed out with a million things in your mind but you still want to go in to warn others, you cannot because the app is simply not well thought out. I'm sure many would simply say "screw it" and forget about it.

  39. Nina-avatar



    Can't really say if the app works because I'm at 0 exposure all the time (which is nice). A (anonymous) risk map would be a great feature to maybe go to places that are safer than others.

    I downloaded the app as soon as it was possible, it worked fine all the time. Few days ago I couldn't open it anymore. Tried few times. Deinstalled it and installed again. All data gone which is a problem for me working in Berlin Mitte I need to know the exposures. Worked one day, now again. Can't use it anymore. Please advise. Using an Oppo Phone with Android. Thanks. Thanks for your reply!

    I and my wife use the app for months always with bluetooth and location on. She got a positive test recently, she inserted it in the app. 2 days after, my app still says I had no exposure, which is impossible, because we have been almost always together. I do not know who is there to blame, but something is not working as I would expect. I believe it makes sense to let the exposured people know about it as soon as the backend knows. Or didn't the backend identified the contact? It seems useless.

  42. Mike McCready-avatar

    The app is working well for me! It updates my risk status every 4 or 5 hours. No errors and no problems! I feel more comfortable since the update to version 1.9.1 which started using v2 of the Exposure Notification System. (I've updated to 1.10.1 now.) In the older versions I had some Low Risk encounters which had me worried because I couldn't explain them and I didn't know when they happened. Now I understand that the very low risk encounters are filtered out. The English language texts are excellent! I didn't expect to see this in an app developed in Germany.

    Got tested and my doctor told me to download the app so I wouldn't have to call in for my results... well I did scan the code and checked a couple times if my results were updated but today the app suddenly didn't show the scanned test anymore. So I tried to rescan it, but that didn't work since you can't scan the same thing twice. So now I have to try to get hold of the doctor before the weekend since he won't call me for the results cause I told him I'll be using the app.

    I scanned my QR code and the test results are still not available in the app 1 week later. They have been communicated to me 2 days after the test by phone. I tried re-installing the app, but the QR code is now invalid. I honestly don't know what the app does. Edit: German health services rely on the app to quickly inform sick patients. But the App doesn't provide those information. Have the functionalities and responsibilities been clearly established with the health services? Constructive crit

    It kinda does what it is supposed to do, but it would be nice to be able to say "hey, I'm waiting for a test. People who were in contact with me shouldn't go to see their grandma until I know for sure I'm negative." Basically the option to say "waiting for test results, stand-by". This would probably break a lot of infection chains, since not everyone isolates until their results come in.

    It has worked as expected for a few months, showing an increased number of exposures a few days after a visit to a crowded place, and making them disappear after two weeks have elapsed. But now, it simply crashes right after the start. I reinstalled, sacrificing the data collected. It was then starting and (rightly) saying that there was nothing yet to report. A day later - again, its screen is showing, then disappearing, then the message "Corona-Warn was stopped" is displayed. That's it. One star. ( App version 1.7.1, Android 7.0 on GS170) Update on 4-Jan-2021: the app is working again, thanks. Cranking up the stars from 1 to 5.

    I want to support this app really badly, but I tested positive and agreed to share the log on my device. Not a single person I know had their status change to red. This includes people I worked with and ate lunch within the 4 days before I showed symptoms. We sat together at the same table for 30-45 mins multiple times. The one positive that I can say is that it works well for getting the results of a test.

    There is no information and obvious way to move your logged data from Android to iOS. Also different phones capture different risk levels, even though they are constantly together. It's not gai ING my trust with that. Other than that, living in a busy area, I constantly have low risk encounters, once red. Since I was tested negative I would have appreciated, when exactly that encounter had happened to evaluate the risk for myself. All in all better than nothing, but far from great.

    So many bugs... I need to keep reinstalling it, because the app hangs up on processes like retrieving data and all you see is the buffering... Just one of many annoying bugs -.- Answer to feedback: 1. Retrieving of test data 2. After re-installing the app I now know, that I am positiv -> now an annoying overlay screen did popup, which cannot be closed... I cannot use the app anymore, because all i see is "thank you" -> also no one I know was notified...

  50. altebo-avatar



    my experience summed up in one word:frustrating! i work for a company in the public sector, offering services having to do with children. outrafged by the govornment's lack of common sense, ignorance of the risks at hand, stating people in my line of work can not be protected anyway, and only minimum pay. i was sent into quarantine by the health department, since we had a confirmed case at my workplace. the health department organized a mass testing. no tan was issued, so this app is useless!

    I can never know whether the app is working as intended since it's never sure whether I've been low risk exposed or not. On some days when it does report low risk reports, I open the app again ten minutes later and it might be either more or less, or no exposures at all anymore. The number appears almost random and I can't check any details as to why it suddenly says there's none anymore. It doesn't seem like it's being very accurate or that it could reliably warn me of a serious threat.

  52. Julian-avatar



    Old Test result that was available before is now stuck at "Data being retrieved" forever, so a new test can not be added without resetting the app... Thus a potential risk would not be detected if you don't have contact with the person again after the reset... This review is for App Version 1.6.0 To Dev-Feedback: a button to delete tests does not exist in the overview and I can't enter the test view because it's blocked due to infinite loading of the old result.

  53. Tomás Cámara-avatar

    Utterly disappointing, pretty much useless app. The most info I've been given is at the level of gossip. Let me explain. The app told me the other day (in my words): "You've been exposed to someone who later reported to have been infected; but no problem, you weren't really, really exposed." Not where potentially that happened. Not how long. Not at what distance. Not at what time. Nothing. That is plainly gossip-level information that doesn't serve any good purpose. Failed use of tax money.

    I have a very bad experience with this app. I've had two test and haven't been able to see either of the results. Health officers told me the results would be available after 24 hours but all efforts to retrieve have proven futile. The app keeps giving me the feedback that test results not uploaded. Utterly frustrating!

  56. Andrew NotTelling-avatar

    Andrew NotTelling


    Utterly useless rubbish. You get no push notification or any kind of visible feedback as soon as you come in contact with someone infected. You need to check the app constantly to find out whether you've been exposed to an infected individual or not. I've found out that I've had a contact with 10 infected people in a span of one week only after I accidentally opened the app. The app itself didn't even show a pop-up message or anything right after the potential risk occurred. That's ridiculous.

  57. MrInboxer-avatar



    I believe a lot of people ONLY installed this app so that they can see the test result, and this app fails to show it. I had my test at Nov 6th, and I haven't got any result from this app till today. I don't wanna be harsh, but if this app can not show the test result accurately, then I think this app is completely useless for most people. Ergo this bug should have high priority to be fixed.

  58. Silver-avatar



    Works as intended however after a week or two the app makes it impossible for my phone to charge. Battery drainage is okay on a day to day basis but then I try to save some by turning Bluetooth off while sleeping and it seems to drain it faster. And then my phone just won't charge at all/ drains faster than it can charge. Once I delete the app it charges normally, which of course deletes all the logs.

    I had made covid-19 test and my doctor said to me that the result can be seen on this app with a simple qr code scan. When I tried to make the scan, I was scanning for 6 days and it never showed the result. I called doctors in the next week and doctor said that the result was there 6 days ago and you have tested negative. I had to cancell all my plans for 1 week and I was not been positive. Please repair this app, it really frustrates patients when the app doesn't work.

    I think the contact journal is a good idea. However, it would be more useful, if it offer the option to record for a place a certain time range and link that specific record to people Good UI, I find the privacy concept convincing, however there should be an option to disclose volontarily to the contacts the specific time in case you are tested positively.

    Lots of people complain about not getting a notification. I answer what would be the urgency. You meet someone and after few days he tests positive. Only then it count as a risk for you, after days likely. I am asking all our you would it make sense to get a notification or to update the data 1000 times per day? I would say no.

    Doesn't work on xiaomi phones MIUI 11, many people have such phones nowadays. Any eta on when this will be possible? I have already reinstalled the app several times. Edit 1: Phone is not rooted. Play store is installed. When I click active logging nothing happens (in the initial versions it was giving some API error) now nothing. Edit 2: google play services v20.39.15. Edit 3: when I click active logging nothing happens, no error messages or anything.

    I hope this app works better than it seems to.. Got my test results 4 days ago and still no update in the app.. Update: over a month later and still no results to display.. now the results section loads ad infinitum. No response from the devs either. Considering that police are now actively using information gathered from resources meant to combat Corona, I think I'll be deinstalling this app.

    Worst App ever. I can not see my results or what I need, the first time my results were never updated. And when I tested positiv I couldn't see my results never in the App. I am working in a hospital with a lot of people who had corona in the Moment and it never showed me in high risk of infection. The only thing this App is doing is wasting my phones battery faster.

I don't know what the problem could be, i restarted phone and cleaned any unnecessary files aswell, but nothing helped. I hope for an answer ASAP. Tho when it works i don't have any problems. 2 stars because 90 percent of the time I can't even use it. It started to happen since the last update (I downloaded it on the 16th of November)

    Generally useful app, but my exposure logging seems to deactivate itself after some days and I have reactivate it manually by turning it on, off and again on. If I wont do that, the app is pretty much useless. Hope there will be a fix.

  69. Daniel-avatar



    Bare minimum implemented very good after some initial problems. Could be so much more though. Why can't I find at least all official lockdown regulations for my location in the app? If the "Datenabschnorchler" politicians get their way I'll uninstall immediately by the way.

    Error 3 all the time and now that I have had Corona test and registered it in the app - it tells me it is already registered on another phone (which it is not) and I need to contact my health care provider for the results. Sorry but this is BS app waisting peoples time instead of helping to break any infection-chain. This is my reply to the answer below from the developer. It's not a positive result that I am trying to enter into the system. I'm trying to find out what my result is ....

    Is it working at all? [Testing] I have been test (at TXL) coming home from a trip in risk area, I've enter in the app the code..4weeks later still says waiting for results. [Tracing] i have been together with (eventually) a positive case for more than one hour at a close distance..the app never shown any warnings in the following days/week. [Tracing] at home since days with no contact with anyone, and everyday shows some new encounter is that possible? How should this app help?

    Is there a way to report bugs and improvements without needing to be a github code contributor? It seems like you need to submit a pull request just to report a bug. Bug: journal days are in German even if the rest of the app is in English (trivial but a bug trotzdem). Suggestion: the chance to rate the risk of encounters with people/places using for example traffic light colour system.

  75. KUNAL KALRA-avatar



    It does the job, but it will be good to have like a timestamp when the exposure happened instead of just having that there are like 6-7 exposures. This will help user to have even extra precautions visiting such places, if it's office or like a grocery shop or so..

    I was forced to uninstall this app, in order to put my QR-Code from my test in it. I had already one test this summer and the app was still trying to retrieve data from that test (this is strange, since I received that result 24 hours after the test on my phone). So there was no possibility to get the data of my newest test on my phone. So I had to uninstall and reinstall it. THIS IS SUPER STUPID, ALL MY "COLLECTED" CONTACTS ARE DELETED NOW. Basically the app is useless to warn others....

    Why this app updates every 24 hour. If you have exposure and the result from tracing is there, I should be notified as soon as possible, not possibly 24 hour later My wife has 4 low risk encounter (ios) and I have none, but we normally have similar routine and location. Seems android app is not working properly

    I love the idea of this app. I'm a British national living in Berlin. I contracted covid-19 2 weeks ago and couldn't enter my results because I have a UK phone number and couldn't call to request a TAN. So anyone I was in contact with wouldn't have known. It's great otherwise. But it needs to open up to non-Germans living or visiting here.

    I'd suggest using the FOSS version of this app instead. It's available on F-droid and does not contain Google "services". You get to view a graph of collected IDs versus days and to export IDs. Otherwise it's the same.

    If the device is running low on space the app stops logging but no info appears until the app is opened manually. Please show a notification instead! Most users won't open the app every few hours so they don't know if it isn't logging.

  81. Fayeluria-avatar



    Edit to respond: The app specifically shows/tells me it is not active. My bluetooth and location as well as the switch for exposure logging are always on. The exposure logging doesn't properly work and cuts out at random times (and shows it when I open the app) and when it works again, it shows that the "exposure logging has been permanently active" which is a lie. I don't feel much safer thanks to the app, now I'm waiting to see if it at least delivers test results properly.

    Replacing my previous review. App is solid, stable. I like the way it uses phone language, despite being a German app. Completely unobtrusive and seems to have no impact on battery life. Got one warning of minor contact, low risk so far. I wish more people were using it.

    Hello RKI, thanks for putting so much effort in this app, which is very crucial in this unprecedented times. I have a problem though, I've been tested for corona two months ago and uploaded my results in the corona app, and didn't delete my test afterwards. Now it won't fetch my results anymore, the loading spinner never stops and I don't have the buttons for deleting my results and upload new ones anymore. I don't wanna delete app's data and thus lose the collected IDs. Can you fix that plz

  88. caveofthesun-avatar



    Doesn't update daily. Works a few days, then stops updating. Have uninstalled it and downloaded it three times now, but never works consecutively. Tired of it. I feel it's only for people with newest tech and fast net. Edit: gave it all permissions, yet still doesn't update.

    Test result notification does not work reliably - which is a KNOWN issue to the developers. Why is that not marked as beta in the app? Testing staff is as unaware as users, communicating to wait for test results in the app! Consequence for me is a week without results from the app as of by now - which is a week in quarantine without need! The results were available, just the app failed! Outrageous! If you are fully aware that the notification via app doesn't work flawlessly, mark it as beta!

    Anonyme Punkte auf einer Karte sollten Covid Kontakte anzeigen. Wenn sie das machen stimme ich zu und werde die App reinstallieren. --- Old comment: The app is next to useless because of it's heavy concentration on data protection. The app doesn't tell me where or when a contact took place. Therefore it's not possible to avoid potentially infectious situations or high risk places. God forbid we'd have too much information. PS: I'm considering uninstalling this because of lack of functions.

    The idea is a good one. There are problems because if it doesn't tell me the when, I may have no idea where I was. Perhaps this is a security thing but a warning when say, I was in a shop wearing a mask means much less than when I spent longer with a mask off. App should also include a standardised location registration as I understand the authorities have problems with the fragmented attendance registers. It could also log symptoms.

Please make sure these functions work! I am very displeased!

    I got a notification that I was in contact with a person tested positive for Covid-19. I went to the doctor and took the test which came out negative. The problem is that the app exchanged ids with other patients, so I got many matches and a high risk again! It would be nice to be able to see how many of the encounters are high-risk and how any are low-risk instead of seeing just a number. Akdo my test result didn't update in app. Otherwise works fine.

    You *MUST* have a German Play Store account to dl this app. For this you need a separate email/Google account, with an address in Germany, not necessarily yours. You do *NOT* need a German payment method though Play asks for one (you can skip that step.) When you open Play, touch the user icon, then 'Add another account,' and 'Create Account,' enter yr info, then 'Choose your Gmail address.' Sounds complicated, but isn't. You must have BT on. The EFF confirms it has no privacy concerns.

    GPS needs to be on, drains down battery even more and other Apps will constantly use it as well in the background. Won't be useful if my phone is off after half a day of usage.

Not very optimal.

    Functions including tracking or notification as well as integration of test result does not work at all. Either do it by enforcing all to install the app by enforcing entry to shops, institutions etc with the app Barcode authorisation, and contact tracing like Asian countries did, integrating the test results propery OR don't do it given the data protection regulation and people privacy. Government is not able to decide which option to choose and only wasting money on such namesake project.

  107. Anaïs Janze-avatar

    A good idea but the app is useless if it can't tell me what exposures are the ones with higher risk. If would be more useful if the app was able to point where you were (eg. supermarket) when the risky exposure happened, so you could avoid it.

    I don't really get what this app is supposed to do if nothing is followed up by consequences. If you get an alert that you're at high risk of having been exposed, you're told to call the local health department. Once you do that, they tell you that nope, there's actually no need for you to get tested so you're basically left with nothing and don't know what's going on. Kind of defeats the whole purpose, doesn't it?

    We Germans are so concerned with data protection that we even are afraid that at least one person always knows all of our data -- and this includes ourselves. So this app barely can do more than data protection. I acknowledge that under these circumstances the app does a really good job using the few technical means it is allowed to use, so from a technical viewpoint it really is a good app. But overall this app is way behind the possibilities a data driven app could do. It isn't even possible to v o l u n t a r i l y provide more personal data for a better contact tracing/tracking. Concluding, this app is a waste of ressources and the money of the tax payers. But the sad thing is that I still have this wreck of software installed -.-

    I wish I could rate the app with minus 1 star, because of the incompetence of the german health care system. I have been using this app for months and asked a close person of me to use it too. The other person received a high risk warning in the app, and we spent at least 3 hours talking to different services who all insisted that she can't be tested without symptoms, which makes the app completely useless. We will both delete the app and keep living as usual until Germany fixes its health care.

    Because of the obsession of data privacy the app is useless.You get a warning that you were exposed to someone who later tested positive and also was kind, healthy and bored enough to report this to the app, without any info on when, where, how long! Was it someone I know or was it some guy in his car while we both were waiting for green light? Edit: Yes, exactly, because of "data protection reasons" this app is doing 1/100 of what it could.But same data protection doesn't apply to google maps.

    Politicians want to convert this app into a centralized trojan horse via an update very soon, after everyone installed it in good faith that it's not used for observation purposes. They're going to tell you they only want access to the data to save lifes and save companies from bankruptcy, but what's going to happen is the same thing that happened with guest lists in restaurants. Right now it's still a useful and safe app, but the voices of politicians are getting louder. Pay attention.
