Reviews From google play store

Only used it one time so far, but far so good. Just be aware that there are a lot of optional extras that are not free. For example, if you want to make ProtonMail work with a desktop email client you have to pay the developer for "bridge" software. That said, I have no real complaints.

Glitch on screen. When update needed it locks me out of all apps and i have to turn off data and wifi then be faster than the app glitch to click the "close all apps" button on my phone. Seems kind of ridiculous for a high security app that is supposed to be state of the art in 2019. One would think there would be coding protocols to stop such tedious issues. If it glitches on a user phone, to the point of being seemingly Parasitic, what other protocols were missed?

Great free service, don't get me wrong, I love ProtonMail, but the "entry" paid plan is far too expensive. Tutanota offers encrypted mail with the same feature set (no ads), for just over a dollar a month. Considering most people don't likely use as their primary email, it's crazy that I have to pay the same as my Office 365 plan (50GB mailbox + 1TB storage) just to get 5GB, 5 aliases, and ability to use my own domain with Proton. Throw us custom domain, 2 alias, and 2GB for $2 and Id be paying

Best secure email provider I've found yet. Decreased the number of stars from 5 to 3 due to a recent update that will now prevent most of the in message photos from loading. Checked all the settings and permissions. All good, except for 80% or so photos don't populate. Turend off VPN, checked to make sure it was loading on my computer and tablet (all good), just not on the app. Even web-based version works great. Hope this gets resolved soon.

I like the idea of ProtonMail, but I'm looking for alternatives at this point. The app does not support fingerprint login. I must manually clear the local cache on Android every time I interact with my mail on a different device. "Move to Trash" is actually "Remove all labels, mark as read, and move to Trash" (but they call this a feature/wontfix). Renaming a label breaks filters that use that label. AFAIK, there is no way to set the reply-to field. Mail from ProtonMail is auto-starred.

A company that purports to value digital privacy and security should support free and open source software. This has been long promised but not delivered. I also have an issue where background sync occasionally re-enables itself. A dark mode would also be nice. Otherwise it's a simple and functional email app that works as desired.

Love it. But having first and huge problem right now. Can not read any emails. Says start PGP Message and a long list of scrambeled letters and then End PGP Message for the last couple days. Ive been a user for years and never had an issue until now. I hope this gets resolved quickly. I reported a bug issue in settings twice already. I cant read the response.

Amazing !! Better than spyware adware Gmail, Outlook and others. ProtonMail is my new main email and I'm proud of it. The speed of the app is instant. No lag. I've never used such a fast responding app. Outstanding. All my friends have ProtonMail now and they are happy. From 2020, I will buy the whole year subscription for VPN. You deserve it. 💯❤️👌😌

I have not (since downloading the app a week ago) been able to send e-mails from the app. As soon as I tap on the icon to compose e-mails, or on "respond to this e-mail", the app crashes Edit 21.09.19 Everything got fixed with the last update. Now the app's great haha. Thanks for the answer!

Much better than Gmail. Unlike the official Gmail app which has had an issue of mail stuck in the outbox for weeks on end, this app actually works. I have no problems reading and sending emails which is all that I expect from an email app. The ONLY problem with ProtonMail app is that updates are mandatory and after an update stored username and password is wiped. Which is especially problematic for an encrypted email without recovery options.

I love this app, one thing I've noticed that has never been fixed is the fact that I sometimes have to clear the trash, spam, draft multiple times because upon refresh everything reappears. Another thing i suggest is, giving the option to delete multiple messages AFTER using search function. In that search screen i can only delete one at a time

I have a ProtonMail account but for some reason I can't make a new account, change my password or verify my identity through phone or email unless I want to see "invalid credentials" every attempt and another person I know has been having the same issue for a month now too. Then there's an option to "donate" to see the same results as if I should invest in something even while bugs aren't being fixed for my time and money to be wasted? Stop making simple things hard.

Good overall, some bugs, some quirks, independent developer (not owned by Google). Labels and folders are different things - this is surprising. A draft is not automatically saved when I close mobile app! Save it without asking me. Reported several bugs to the tech team. Almost abandoned the app b/c I was not able to send emails reliably - but, there are few alternatives. We want reliability first (not losing data, always delivering to recipients), features second. Solid 3/5, would recommend.

I updated my rating due to the response and actions taken on this excellent product. I love Protonmail and absolutely recommend it to everyone. This temporary bug will be fixed I am certain. Doesn't happen so far since reinstall. Actually the same thing happened to me. I got the same error loop that wouldnt go away. Thought I had a virus. I had to uninstall and use a browser to log in. Developers: Great product but need to fix this temporary issue. Other people are experiencing this too. Bill

It's a great service but unfortunately I didn't update the app for long time and when I try to open it, it showed an error about updating app frequently which I couldn't get rid of it until I restart my phone and now I just update the app for Android.

It's a usable app with annoying bugs. All bugs have been reported but feels like it's not ready for prime time. Two current bugs are attachments loading issues when viewing email and major sync problems when using web interface. Filter support should also be added. Not a lot of options in this space, as a contributing user I would like to see it get better. Signed up for beta to help where I can.

The android app is not working. Actually, I think that the current version having some bugs, because I am getting the new notifications about the new emails, but it's not opening the associated emails in the Android app. . Pretty strange. . I should say that I can reconsider to change the rate if the problem is solved. Thank you!

Protonmail doesn't connect. It's telling me "No Connectivity Detected (retry)". I have connectivity on everything else. It started Nov 2nd. Update 5 Nov: it now is working as it should. Have no idea what went wrong for 3 days.

User friendly and good app. The security is top notch. It's pretty neat. :) Changed it from 5 to 4 stars since there has been some data loss related bugs that were a bit concerning. Data preservation is so important as well as being confident what you upload actually get sent. I hope this is an exception (why it's still 4 stars even though the issues are serious) but I'll update the review accordingly.

Brilliant! Works flawlessly, and exactly as described. Functional, without frills. Its simplicity is highly refreshing - an app which performs its intended function with the accuracy and efficency on a par with the finest of Swiss watches, but without the bling found on modern impostors. Highly commended for sticking to your brief. Richly deserved five gold stars from a very happy and contented user. 🍻

Phone locking bug when outdated! This app will fail miserably when outdated. It tried to force me to update by locking down my phone - switching windows to update was impossible, killing the app neither because list of windows open was closed by the app itself telling me to update. Otherwise it's a simple and nice mail app and I hope the developers won't have such a painful bug in the future

I had to uninstall and reinnstall this app twice now because it keeps freezing up with notifications. It keeps flashing but nothing happens when i click on them, just like Kay Tzu who posted below. Exact same thing happening to me also. Very frustrating!

Have been using ProtonMail for about a year or so now and it's been a fantastic experience. Much better than gmail and boasts plenty of useful features I haven't even touched yet. One thing I will note is some emails with embedded content simply don't display on the mobile app, but they do on PC.

ProtonMail overlay User interface stating "you must download new update" before log in bricked my phone. Clicking 'ok' doesn't make the pop up go away. You cannot go into settings to turn overlay off because the pop-up with the message won't stop on Oneplus 3t series. Only re-starting the phone kills the pop-up. Also why force people to download new updates and not allow them to access email? That's ass backwards customer service.

Only encrypted if you pay a monthly fee which was a bit of a significant waste of time. I can understand free being stripped down version but the whole point was to send encrypted mail which is a paid extra!

Crashes often and in some instances very predictably: just try deleting several messages in a row by swiping. Very slow to show the inbox messages when opening the app. UPDATE: Reinstalling the app fixed the slowness, also seems more stable.

I like the app, but one thing annoying me. When i receive a mail i get a notification on my phone. If i read it from my computer and i receive more mail after, I still have this mail i read in the notification list with the new one. I have to click on the notification to clear it. When you send a notification on the phone you should check if the mail before got read and remove it.

I love this app simply because its another alternative choice to the same email websites we have seen for literally decades. I haven't used it very long or very many times but I can tell it's very user-friendly.... And overall it just looks like a nice format.

Need accees to spam filter in app, so it can be managed. Don't have time or interest in waiting until I'm home to fire up the old computer to fix this. Very annoying that you filter my email without notice. Missed many emails before seeing them in Junk. Also need ability to turn off filter from app. I'm not an idiot. I know which emails to open and which to send to Junk and can do that. So this would also require the ability to long-press and select Send To Junk.

I am using Protonmail Plus, but I am missing some features like calendar and storage. Also a Linux application for vpn would be nice. Nevertheless it is the best one out there in my opinion. Very recently I was told that they are exually working on storage- and calendar application.

Good app, I haven't had any issues. The feel is somewhat Windows 2000, but it all works. @protonmail: One thing I'd appreciate is the ability to put the Archive button in the topbar once messages are open. Now I'm just deleting messages I don't want in my inbox. Pulling down a dropdown menu is already too much effort :)

woke up to my phone burning hot and this app was stuck in a loop where it said i needed to update the app to use it. press ok, the same message pops up. when i try to kill the program by going in to settings the program pops up again with the same message saying it needs to be updated to be used and i had to force shutdown my phone. terrible design. edit: the app can't be updated. truly terrible everything.

it's great however the lower rating is be cause recently I was informed I needed to update the app as i opened it. it aggressively blocked any attempts to shut the app down or to open the App store for me to be able to update it. I had to restart the phone in order to access the App store

It's a great nonsense when update notification is on. It's crazy that you can neither turn it off nor use other apps when it pops out. And I'm disappointed that I cannot sign in as the second free account.

Best & most reliable email encryption app you can get.. Includes no in-app spyware trackers within the app. PROTON'S choice not to include ANY invisible in-app tracking is HIGHLY COMMENDABLE & sets the bar high for all other webmail & VPN services,which almost all have numerous invisible trackers in their apps thinking users are too stupid to figure it out compromising, storing, sharing, selling your info from inside the app when U think you're safe! PROTON HAS SET A NEW ETHICAL STANDARD 100/100

I cant create an account on both the app or the website and when i try, the app stop or the website get me back to the first page. after a few try, it say my domain name is used and when i try to log in it says invalid credential.

Suggestion: don't include trash items in search results & have separate search for trash. Currently it clutters search results unnecessarily. Only solution is to empty trash, but I want to keep those items just in case.

There's simply too many paid restrictions. No usage of and now you can only use ONE free account with the mobile app. There are better domains to use (like with so many more features for free and PGP is enough for encryption. I'm sick of Swiss companies that charge out the @$$ for services like they're made from gold or platinum. Might as well go to Lavabit for this level of pricing. Recommend everyone to look around for alternatives. Protoncould at least offer a lifetime sub.

Can not download pre-encrypted files. If you receive an attachment that is already encrypted (i.e. sending a PGP attachment), this app treats it as being encrypted by ProtonMail and not the sender, and will fail to download.

No any other mail client from now on. I have to edit my review for letting you know that the app has a problem. Ever time I write an email, if I stop writing for a while and the phone goes in the blocked mode, I lose everything I wrote.It deletes everything 😢.

Would be nice for the vibration pattern to be the same as other mails apps like GMail or K9 Mail. Currently the pattern is the same as receiving a text, a bit annoying. Notifications aren't cleared automatically when the email is read from the web interface.

Yep Gmail can go stick it up the a***. Whenever I book a flight or a bus ticket to my Gmail, Google are all over me asking me how my journey was etc. They shouldn't even know! ProtonMail all the way. Thank you for your excellent service!

The previous issue I had was fixed rather easily. Now that it functions, I love this app. Give it a shot if you feel like de-Googling your life just a little bit.

Bad design. 2019 and can't have two accounts? Fine. But when I log out of one of them it takes me back to enter all credentials. That makes no sense. Why give the option of adding another account when I can't switch between them on the fly after logging out of one of them?

Surprisingly good app compared to a giant as gmail. The main drawback for me is the battery usage, this app uses about 4.5% while not being used that day. You could probably tone down the sync rate since i always get my email 2-5 min earlier on protonmail than gmail (linked acc).

I cannot find a way to have AP show on my opening page in order to access protonmail. I am also concerned that only way I will be able to communicate with others is if they also have a protonmail account. I am sure many of my contacts would resist that idea. Am I correct?

Not able to login as I was told I've been hacked. Emailed the developers but so far I'm still not able to login even after updating. Why does it take so long to get an answer? Is it possible that Protonmail can be hacked? Bizarre!

For two weeks, my cell & tablet suddenly both say NO CONNECTIVITY DETECTED before i put in my username or password!! I've changed NOTHING. It worked for two weeks then it has NO CONNECTIVITY! Frustrating.

All in all works fine, but it's not all ways sync to the desktop. When I move mails in an folder on the desktop, some mails are still in the inbox in the app.

Latest update made emails unreadable so til new update, I guess I'll have to check my emails through their website for now which is gonna be a hassle when Im out. 😩 Still <3 protonmail, but plz fix 😶 Edit 10.2.19 : I had uninstalled after last review. Reinstalled today and everything seems back to normal, woot!

I moved from Gmail to ProtonMail. I haven't experienced anything which makes me regret this move. Knowing that you are in control of your conversations makes me feel more comfortable. Sharing my conversations with the world was the last thing I wanted in my digital life.

I love the app these guys have made. It's top notch in UI and I greatly value anything that helps with security in this day of data trading and privacy irradication. Thanks ProtonMail, you rock!

Love it. Keep at it. I went premium. The more you can tear down Google the better. Google is evil. I'd love a protonstore to get apps from that rivals thebplaystore. I'm transition away from Google as much as possible.

Great app GUI and high security. It verifies the server CA. I normally disable unnecessary CA until needed. The app wouldn't run until the right CA enabled. Only problem being it shows "no connectivities detected" error which threw me away.

Getting WORSE. An app defined by privacy/security now just ignores ur PIN. So sad. Good app for JUST email BUT Defeats privacy if you have to use typical apps for calendar ... Why not built in? Also name and photo etc visible on review ... Guess privacy not taken seriuosly. Glad privacy is a desire for me, not a need.

Wasted half an hour trying to send an email but "failed to login" until I got home and used my pc browser to login first. A warning before update would be appreciated. Other than that ProtonMail is doing a good job.

Excellent email app. Fast, responsive, emails displayed correctly and nice clean UI. Add that to privacy and email encryption and it's a winning combo.

I have been using the free version of this app I guess about 2 years. I love it, no problems so far. Slowly trying to move away from Gmail.

Awful.. just awful.. it crashes.. it doesn't send emails when you think it did.. messages in the draft folder disappear randomly.. Just really stay away from it. It has been consistently bad and no sign of improvement. Use pen and paper instead.

Perfect except your update notification took over my phone, was always on top no matter what I tried ??? Battery died and killed it overnight... Hope that never happens again !!! Still a 5 * App !

I love it, but it *really* needs a dark theme and a way to resize message text. There are readability issues.

Excellent app and service. Have been looking for just this secure email. Just one problem - my pin number gets stored on the clipboard each time i open the app. Huge security hole - needs fixing pronto

I'm having issues to where I'll receive a random peice of mail that i recieved a few days prior. It doest happen all the time, probably once every week and a half or so. Almost like the mail copied itself and the other one was late.

So far has no issues and works great. Keeps your data private and encrypted. It is a must have it app.

Bug: start writing a message. Leave app. Click email link in other app which opens protonmail. Your old (lengthy) message has not been saved to drafts.

Stable, easy to use, covers basic mail app funcionality and allows to lock the app with additional PIN and fingerprint. Keep up the good work.

Mail arrives and you get no notification. Unreliable. Can't use as main email and however you only get 500 free mb, if you want more you have to pay. According to the helpdesk, you should spend time trting to fix it yourself, under their guidance. TRY MAKING SOMETHING WITHOUT BUGS IF YOU WANT TO BE TAKEN SERIOUSLY. 1 star. My patience ran out.

Stop making it impossible to create another account. I deleted my old one and now im left with no email. Your email verification option crashes the site and the phone cannot be used to verify because its registered on the old account. Very poor coding. I will look for another email service.

I love protonmail! Goodbye and good riddens to Gmail, Protonmail is way better and the app is almost as robust as the desktop version. I will happily pay for encrypted email now and into the future!

"cannot be used until it is updated" - can't even close to dialogue box, can't even force shut app because it keeps popping up

This app will not download or send emails. Just gives message "no connectivity detected". Used to be great, now it sucks.

The best in encrypted email. Easy use across devices. Good for when you need to send important info and any personal data.

Tried everything, but I am just not getting notified about new mails on my phone. So I had to forward them to another mail account. Useless.

Thank you so much, it's such a wonderful service! And the app is great. I just have one request : could you add an option to "mark as read" directly from the notification pop-up? :)

Great email client for even better email service. 4/5 because I can't switch easily to other account without paying.

I like it, would be nice to have the "UNREAD/READ" option available while the mail is open instead of having to go to the inbox, check it, then mark it unread.

"Gateway is unreachable" is resolved now. It must be temporary server issue. Ratings changed. Thankyou

Great app, enjoying the service and more features worth paying for. Waiting for Agenda and Contact features so we can sync with other devices and computer.

High quality. Very secure and easy to use, and unlike gmail they don't parse your emails and sell the data to advertisers. Edit: looking forward to that proton drive :)

Created an account, then removed it and made another address and it said my phone number is taken. So couldn't create one or get into the old one. Kind of dumb.

I tried composing an email but wanted to save it as draft, so I exited and it prompted to ask me if I wanna save it as draft? I tapped yes and did nothing. :(

While I open an email with attachments it keeps refreshing the content which means that it's impossible to read anything as the scroll resets all the time

love the concept and functionality, will get a paid plan sooner or later. but im missing a function to filter all unread messages, thatd be really handy.

I only get notification when the app is open and active. Please fix this as I have missed some important emails. Then you will get 5 stars.

"free and with IMAP features" description reads. Only, you can NOT connect to a non-protonmail IMAP account with a free account! ☹️

It's great, but needs a tablet mode. I like to browse emails on the left and read my selected email on the right.

Syncing or refresh issue. When moving or deleting emails it will still be inside the inbox or draft even though I deleted it or move it to a different folder.

Works great until you go to reply back to an email that goes to a blackout screen, checking more thoroughly found out all lower buttons being return mail return all or forward none of them work

Needs a dark theme. Very bright to use at night Need to support biometric, not just fingerprint authentication. Proton Mail does not support biometric authentication on Pixel 4 yet.

From time to time app logs me out and/or resets my security and unlock settings. I have to enter my long password again and again, and configure my PIN and fingerprint unlock.

App is amazing, ProtonMail is the best email experience I've ever had. 10/10 without any doubt. Only issue: Can you make downloaded files with different icon? Downloaded and non-downloaded files looks the same.

App kept opening telling me to update, only way to escape is to reboot, also doesn't mention that you can't send large attachments

Since last update I can't load images in mails, already tried deleting the app data but still images don't load. Update: now works fine, thanks.

Tbh. I created an account awhile ago, but it seems like I can't receive or simply don't receive emails to my email at protonmail. I will rerate when the issue is solved

I've been using protonmail for a few years, never once have I received any unwanted ads, junkmail, or other B.S. that comes with gmail or hotmail. Worth 10 stars.

I love it, except for the way it acts when it's in need of being updated; it effectively locks one's phone...

Brilliant and secure. If you are wanting out of Gmail or those free (snoop) services, this is wonderful. Support is there and if you pay (understandable) you get more options.

Waste of time I tried to sign up with my same phone number but I didn't worked it says you can't sign up using same number plus I don't have alternate number it's worthless service for me.

I received excellent help from support when I couldn't find the labels/folders menu which is found by selecting your account name under settings.

DO NOT USE FOR BUSINESS MAIL. Very poor stability and cannot access email refused password, not interested in protons inquiry, attempted to use multiple devices, wrong credentials, we even used multiple browsers.
