    I love how easy this app is!! I have endometriosis, so making a simple app, helps me out a ton!! All I want to do, is document my periods, how I feel, symptoms I'm feeling, and have other options. I like that they made this app simple, yet very personal. I like that you can use a 4 number password, to keep it private. I will continue using this app for the rest of my periods.

    It tracks me right to the day. I love going to the doctors and being able to pull up my history. With all that I have going on in my life, I can't keep the days straight. I've been using it for 3 years. And all the updates have just made me love it even more. Trust me, you and your body won't be disappointed.

  • Indispensable app

    by Mel312

    This was one of the first apps I got when I got my iPhone 6 years ago! This last update has made it even more appealing to use (the last format was a bit blah but I still used it a lot!) knowing when my period is coming, ovulation times, data recording, it is all amazing! Thank you so much for making my life a little easier. And that's what good productivity apps are all about right?! Get this app! You will never regret it. :)

  • Great App!

Great for all women even if you're not trying to get pregnant-- I'm not and I've used this app for years to help myself understand my natural cycle better since I "quit" birth control. In a few years, though, I will be happy to use it when we are trying to conceive. FIVE STARS.
