Best design, accurate, & informative!

This has the best skin choices and the most mature look to it! Other apps where too child like in their design. I wasn't sure if I was designing a room for my 9 year old daughter or if I was mapping out my period! I also like its options for journaling but not having it be the main focus. Too much focus on socializing and journaling found in other apps, lets just get to the point. I wish I could mix the hormone horoscope with this app then it would be a practically perfect free app! I have been using this for 2 yrs now. My period fluctuates from 26 days to 34 days. I know this because of this app! It is accurate and super easy to use. I am now able to predict and even schedule fairly consistently around my PMS cycle, which unfortunately is severe.

Love it!

Very helpful app and have used it for a couple of years now. Up until now, there have only been minor ads in the app. These could all easily be closed by clicking the little X in the corner. No biggie! Now, not only am I forced to watch the same ad for Game of War every time I open the app, but I can't close it for a few seconds. This ad for that stupid game shows up in every app I have. If those app's ads have not convinced me to download that stupid game, getting it while I'm trying to record my period, which is when I'm the most irritated anyway, is not going to encourage me to download the stupid game. Obviously the makers of that game are spending a lot of money to promote their game. All it's doing is making me not want it! Lose the long ads. Lose the ads that I can't click out of right away. Lose the ads with sound!

Amazingly accurate predictor

For years, I kept track of my period, moods, and hormone-related physical state with an Excel spreadsheet. Now that I switched to this app, all that is infinitely more easy. The mood charting and multi-month period predictor are my two favorite app tools, because they let me know in advance to be alert/prepared/gentle for myself. The best part is how the app gives push notifications so I don't even need to open the app for it to help.
Another thing I like about this app is that is serves as a nice semi-private place for women to talk about IUDs and other alternative modes of contraception. I like that.
The only downside is that the interface and look of this app is a bit clunky. But it works perfectly!
