requires following permissions on your android device.

approximate location (network-based)
Allows the app to get your approximate location. This location is derived by location services using network location sources such as cell towers and Wi-Fi. These location services must be turned on and available to your device for the app to use them. Apps may use this to determine approximately where you are.

precise location (GPS and network-based)
Allows the app to get your precise location using the Global Positioning System (GPS) or network location sources such as cell towers and Wi-Fi. These location services must be turned on and available to your device for the app to use them. Apps may use this to determine where you are, and may consume additional battery power.

view network connections
Allows the app to view information about network connections such as which networks exist and are connected.

view Wi-Fi connections
Allows the app to view information about Wi-Fi networking, such as whether Wi-Fi is enabled and name of connected Wi-Fi devices.

pair with Bluetooth devices
Allows the app to view the configuration of the Bluetooth on the phone, and to make and accept connections with paired devices.

access Bluetooth settings
Allows the app to configure the local Bluetooth phone, and to discover and pair with remote devices.

allow Wi-Fi Multicast reception
Allows the app to receive packets sent to all devices on a Wi-Fi network using multicast addresses, not just your phone. It uses more power than the non-multicast mode.

connect and disconnect from Wi-Fi
Allows the app to connect to and disconnect from Wi-Fi access points and to make changes to device configuration for Wi-Fi networks.

Allows access to the list of accounts in the Accounts Service.

full network access
Allows the app to create network sockets and use custom network protocols. The browser and other applications provide means to send data to the internet, so this permission is not required to send data to the internet.

read phone state
Allows read only access to phone state, including the phone number of the device, current cellular network information, the status of any ongoing calls, and a list of any PhoneAccounts registered on the device.

run at startup
Allows the app to have itself started as soon as the system has finished booting. This can make it take longer to start the phone and allow the app to slow down the overall phone by always running.

draw over other apps
Allows the app to draw on top of other applications or parts of the user interface. They may interfere with your use of the interface in any application, or change what you think you are seeing in other applications.

prevent phone from sleeping
Allows the app to prevent the phone from going to sleep.

modify or delete the contents of your SD card
Allows the app to write to the SD card.

install shortcuts
Allows an application to add Homescreen shortcuts without user intervention.

uninstall shortcuts
Allows the application to remove Homescreen shortcuts without user intervention.

In-App billing
In-app Billing on Google Play provides a straightforward, simple interface for sending In-app Billing requests and managing In-app Billing transactions using Google Play.

receive data from Internet
Allows apps to accept cloud to device messages sent by the app's service. Using this service will incur data usage. Malicious apps could cause excess data usage.

activity recognition
Allows an app to receive periodic updates of your activity level from Google, for example, if you are walking, driving, cycling, or stationary.

    It's easy to work, tried another app, hated it so went back to this one. The ads are the only down side.

  2. guest-avatar

    It's not reminding me three days before like it's set to do. The last three months it hasn't worked.

    Seriously i asked for one thing get a notification that my period is coming up and what do i find awkward moments and for several months this thing is busted

  4. guest-avatar

    I've used it for years, but there is a bug where if you do not start your period on the right day, it deletes the previous start date. I've learned to write down the previous date, add the current start date, then go back and re add the previous start date. Hard to believe it's not fixed after so many years.

  5. guest-avatar

    Been using it for years. Simple and convenient.

    At the age of 46, I used this app for only one month and got pregnant on my second month. My humble request now is adding the option of pregnancy and getting us a pregnancy tracker

  7. guest-avatar

    Check your battery status in your phone settings. This app running services and needs a lot of permission. Always trun on background and consuming a lot of battery power for nothing. Unliked

  8. guest-avatar

    I've used this app for years. Now all of a sudden they want advertising ID, location and 'other data' to track my cycle. That's a bit much!

  9. guest-avatar

    I'm sad I lost all my data. Again. Had my phone replaced and apparently you can't get it back. I'm using fitbits tracker going forward as that backs up.

  10. guest-avatar

    Not happy with the increase in ads. Emailed the developer months ago with questions and never received a reply. Why would I pay for no ads when I can't get a reply?

  11. guest-avatar

    Love the app , have lost all my backup after reinstalling the app.... Why dont u guys just link the app with the user's email id so that the backup is saved there...

  12. guest-avatar

    I love the app, but I recently switched to iPhone & can't find it in the App Store. I only find My Days X, which I'm not a fan of.

  13. guest-avatar

    I like the free app but paid for an upgrade and I still get ads...

  14. guest-avatar

    Useless. You don't need my location every time I open the app. In fact, you don't need it at all. Developer said you can deny location permissions, but there is only enable location, no deny button. I have an ad blocker.

  15. guest-avatar

    I've recently switched to a new device and have transferred the backup file into my new phone. However every time I try to load data from sd card, it shows "error reading backup". It's been like this for more than a week and it's really getting on my nerves. Tried backing up to email and it doesn't work at all. Been using this app for years and really don't want to start the app fresh. Wrote to the email provided and didn't get any response too. Would be good to get some response from here. Will update to 5 stars if my problem is resolved.

  16. guest-avatar

    I have used this app for five years. It's great to keep track. Nifty features. However, after EVERY update, it loses my data. Even with the backup options, and I used ALL, I was never able to regain any of my data. There's a reason why the data is needed, the devs must have understood that when they decided to include data backup options. I am uninstalling it. I needed the app to help with tracking cycles AND maintain previous data, it failed. Repeatedly.

    Charlene Whitely


    Highs and lows. This app used to be spot on, now, it's all over the place. I used to be able to keep the data between devices....not any more and more recently, my cycle is every 25 days and it will not override like it used to when i enter my actual start and end date. it shows 32 days no matter what I put. To test it out, I put outrageous numbers in and it stays at 32.

    I've been using this app for the past few years, and even recommended it to several others, including my daughter, who now has it also. I do have one suggestion: expand the birth control reminder to include an option for those of us who use methods other than the pill. If you use a patch, or an IUD, or some other form, then the reminder option is essentially useless. So, if you could make the reminder customizable as far as how often (not just daily, but weekly, monthly, etc.), and also make the reminder itself able to say something other than 'take pill', i.e. "change patch", "check threads", etc. that would be a really great improvement. Thanks!

  19. guest-avatar

    I have used thus app for several years. I wished there was an option to reset the password instead of uninstall and reinstall, just to lose everything. I will just uninstall and go back to the old-fashioned way of just writing everything down. After reading all the comments of how the update has screwed people. This app is no longer for me.

  20. guest-avatar

    It's a good app but I'm completely against the new Privacy, Age and Personal Data collection checkbox. Theresa no option to use the app without "agreeing". This is against EU privacy protection. Why is the app maker asking us to give him our personal data? What is his intention? This is private personal information and I do not consent to share it.

  21. guest-avatar

    I've used this app for years w/o problems or concerns, but in recent months it has become very aggressive and intrusive about privacy. And now it tries to absolutely BLOCK my usage until I accept terms of a new, intrusive EULA. There is no non-sinister way to interpret that. There are lots of other options out there to try.

  22. guest-avatar

    I've used this app for years with no problem. For the last couple of months, tho, it's caused my phone to take 15(!) minutes to restart with the infamous "optimizing app 1 of 1" message. I've uninstalled and now my phone reboots in a flash. The random ads are also irritating.

  23. guest-avatar

    I used this app for many years and now all of a sudden it's getting my period start dates wrong. I will no longer be using this app.

  24. guest-avatar

    I've used this app for a long time. Many years. I got a new phone few years back and I had paid for premium version, only to discover the creator had changed their policy. I was treated rudely and like I was an idiot in the public chat room when asking about moving the app to the new phone and realized that just because I paid for it, didn't mean anything. I switched to a better app. Goodbye.

  25. guest-avatar

    Lost my period data twice within the past 2 years. Tried transferring previously emailed user data by email which didnt work. Says cant find a. app the open file but the app is installed. Then it deleted a whole year of important notes and period data when I attempted to upload the old data file. I had very important notes there just in case my physician needed it. Now its deleted even no record of last period which has now.become irregular. I'm very disappointed!

    It's about time I write a review.. I've used this app since 2009. I've tried others, but they just don't do what I need. It's simple, easy to use, and doesn't muck around giving silly facts and quizzes. I always come back to MyDays. I seriously love this tracker.

  27. guest-avatar

    Used this for years with no problems. Finally upgraded, and now it doesn't work. If I tap on a day nothing happens, no menu of options, nothing. The only thing working is that it WILL scroll through months with the left and right arrows. Really frustrating.

  28. guest-avatar

    Used this app when tracking my period and my last pregnancy. I was able to go to the doctor and give her my exact dates of last period. The app knew exactly how many weeks pregnant I was and predicted the due date correctly. Great app!!

  29. guest-avatar

    Domonique DeShields


    This App keeps force closing the second I open it and the amount of Ads is ridiculous! The app is very accurate WHEN it works.

  30. guest-avatar

    Buggy - used this app for a long time. Recently the ovulation reminder comes up every hour. Like, why? And ads pop up haphazardly. Really annoying. Back button kicks you out sometimes and you have to reenter password.

  31. guest-avatar

    I am submitting my review before the new update. Ive been using an old version for years and I like it cause it's simple. So I really hope the new version doesn't bring complications :) but I'm happy to give it a chance!

  32. guest-avatar

    read through the privacy and terms and conditions and did not find it appropriate for the amount of information and access it was asking for just to track my period. uninstalled. always read the fine print.

  33. guest-avatar

    Why isn't my backup for Dropbox available anymore? I can't restore from there as I don't have the option so now I've lost all my data and have to start again. Not to mention there are 3 different apps, all the same from the same person? It's so confusing.

  34. guest-avatar

    Have been using this for years but recent update is causing real pain every time I restart my phone. It invokes optimising app process at startup and takes ages to finish. Hate to say but uinstalling now.

  35. guest-avatar

    Been using this app for several years. The only thing I wish it had was a way to mark pregnancy so it won't count the several months between last period and next period (could be 18+ months) as part of an average cycle length.

  36. guest-avatar

    Nicole Francesca


    I loved this app so much but recently the widget is setting the days on 88 to my new cycle everytime and it won't count down any more I have to remove the widget and ad it again but then after 10 min it is shows 88 again

  37. guest-avatar

    good app until recently. now i cant even open the app, it crashes at every attemp. when i could use it i absolutely loved it.

  38. guest-avatar

    JamminZoe Meade


    It would be great if the pill alarm came up at the time i set it for as opposed to 3hrs or days later. it works when it feels like it.

  39. guest-avatar

    dont bother. it is just ads now. hard to even do anything. I have had this app for many years but going to delete it. not worth the hassle.

  40. guest-avatar

    The current update that was done today keeps force stopping the app repeatedly even when it's not in use.

  41. guest-avatar

    its a great app. wish it offered an account option. i lose data everytime i switch to new phone which sucks.

  42. guest-avatar

    The app used to be great. But it no longer works with lgg4

  43. guest-avatar



    Tried to password protect and it won't acknowledge the password. No reset/recovery option.

  44. guest-avatar

    Fix this app, it keeps force closing every 10 seconds when app is NOT being used.

  45. guest-avatar

    The ads are the reason I'm over it. But it's a good app. But too many ads.

  46. guest-avatar

    really accurate, been using for awhile now. really like it, very simple

  47. guest-avatar

    i keep getting a pop up message that says the app has stopped working but i dont even have it opened

  48. guest-avatar

    This app is the reason why i have my second child (my daughter) #i love this app#

  49. guest-avatar

    unable to transfer data to the new phone.. i been using for the longest time... pls assist...

  50. guest-avatar

    would have given it 5 stars but the dates are a day off. it is showing aug 10 as a friday when its Saturday. cant find a way to fix it.

  51. guest-avatar

    I had to uninstall. This app kept popping up with a glitch flashing on my screen

  52. guest-avatar

    l have been using this app for soo long and it's good...i have never regretted using it.... very nice and accurate.

  53. guest-avatar

  69. guest-avatar

    This app used to be reliable & I used the countdown widget all the time. Now every time my phone resets the widget changes to a countdown of 88 days, I have the latest version, have removed the widget & put it back ... but to no avail ... this is so frustrating. Solved with your support, thank you :)

  70. guest-avatar

    no longer works properly

  71. guest-avatar

    great app

  72. guest-avatar


  73. guest-avatar

    Why does it keep reseting?

  74. guest-avatar


  75. guest-avatar

    Your ads are out of control and the widget has completely stopped working.

  76. guest-avatar

    This app use to work well, 5 🌟 well. Now, when I close the app, music plays w/ no indication of where the music is coming from. I found that this app was the culprit after opening my app list and force stopping each app until the music stopped. I checked the permissions list for this app and they are ridiculous. Why would this app need my location or contacts, among other silly permissions, to help me keep track of my period? Makes no sense.

  77. guest-avatar

    backup data, save data, or load data the options are there I have used my DS card and my email. both options could not retrieve whatever file was sent to those locations. I know my way around a phone I have the note 9 been using this app since I had the note 3 and alway had to start all over every year I got a new note. even trying the password thing but it's not link to anything to save my data. I'm some over this app. it's a waste I have seen better with much better functioning.

  78. guest-avatar

    awesome app

  79. guest-avatar

    This is an excellent app, I love the notes you can add along with tracking the cycle each month. I tried to search through my notes though but can't. Is there anyway to add a search bar to search specifically for something saved in a note? Also, is there any way to be able to add multiple notes to the same day instead of a long note? Pllleeease😁🤗😋 Thanks!

    Great app. Have used it for almost 10yrs. Haven't updated in a while because I prefer the look and feel of the older version. The widget works great in the older version, without the nonsense of having to turn off battery optimization.

    App takes a long time to load. Didn't do this before.

  87. guest-avatar

    10/9/18- THE APP WON'T OPEN SINCE UPDATE! I HAVE 6 YEARS OF HISTORY IN THIS APP! PLEASE FIX IT FIX IT FIX IT! The user friendliness and smoothness and ease of operation is gone! If it doesn't go back to how it was before this last update I will definitely be deleting this app despite having it since day 1!!!! Plus the preference menu setup is way less user friendly whereas before you could just look and see exactly what you wanted right away because of the setup and colors. Now it's boring and has no colors. As well as the calender has become dull despite what colors you choose. And how about some pink & purple!

  88. guest-avatar

    Latest update crashes constantly while not even in use. Keeps putting errors on my screen despite not even being opened or used in weeks. Started with an update that downloaded this morning (October 9th)

  89. guest-avatar

    It is constantly crashing and I am not even logged in....

  90. guest-avatar

    Used to be simple and easy to use. Now they try to collect private information + display too may ads. Uninstalled.

  91. guest-avatar

    Andrea Bustamante


    STILL ASKING TO TRACK MY LOCATION which has nothing to do with my period. Why? Are the designers going to bring me pads or tampons when I'm about to start? I see no valid reason for them to need to track my location. Why would any developers need to know where an ovulating woman is, regardless of relationship? Seems pervy to me.

  92. guest-avatar

    Elizabeth Locke


    I really liked this app until you had to start entering a password. This seems unnecessary. Is there a way to disable this?

  93. guest-avatar

    Shemetrius Davis


    It would have received A LOT MORE stars and better review if there was a way to keep track from one device to anothet without everything deleting. When ever i get a new phone or even sometimes when my phone updates this app will delete everything and i have to start all over. You should consider setting it up to where you log in so the app can store and keep the data from one device to another. Just allowing the app to be locked does not count the info still deletes.

  94. guest-avatar

    Been using it for years and I love it! Just wish there was less ads when I go to enter my password and also I really wish it wouldn't take up so much data usage any help on that end?

  95. guest-avatar

    don't allow me to agree to the policy can't click on agree

  96. guest-avatar

    Otherwise love it, but I just changed phones and lost 4 years worth of data, cause app doesn't load the data I backed up to my SD card.

  97. guest-avatar

    Katerina Malakhova


    All the data has disappeared after the update! After 4 years of usage it's empty!

  98. guest-avatar

    Now you force me to us my data or the app shuts down? Ridiculous...bye...

  99. guest-avatar

    So many ads and now ap wants my location and other data? Bye!
