    I love using this app because I know when to start preparing for my period. There are a couple minor things though. First of all when I got this app I was so confused on how to use it. When I was on my period it said like "19 days left" or something and I thought "My period will end in 19 days?" I have figured this out though. So it would be nice if you could do a small tutorial video. Second of all, I applied a password but a couple months later I tried logging in and it said my password was incorrect and I know I did it right. I had to delete the app and download it again. Not sure if this is normal or not. But still I like it and would recommend it to friends.

    I have never been able to properly keep track for whatever reason. This app has been great in keeping me on top of it. No more guessing! I love how it estimates the days for me and averages everything out. Easy to use, minus a star for all of the ridiculously annoying pop ups that fill the screen and/or suddenly appear when you go to click on something. Edit: I've apparently been using this app since 2011 and I still love it! They got rid of the pop-ups and I love how you can sync it with your calendar...(is that weird?) Anyhow, highly recommend it. Updated to 5 stars!

    I selected this app when I upgraded my phone because of its ratings/ reviews (I previously used another period tracking app). You have to click around more to enter things on the calendar- this can be annoying, and I feel it is not as user friendly as it could be. I do like the variety of symptoms this app gives you- that is helpful for me. The main reason I have not switched to a different app is because of all of the work I have put into this app to log my periods.
