Update: Not changing the rating, still a great app. I actually do recommend it to others. The core of the app, the period tracking, is free and phenomenal. All the extra stuff - lessons, data analysis, community forums - are behind a monthly subscription. It's a little annoying but honestly it all works out. I paid for it for a year and then realized that I never used all the bells and whistles so I stopped. Worth it if you actually interact with it. Overall this app has really helped me :)

It's an overall great app to help young confused teens understand the concepts of growing up. I love how friendly everyone is to each other and how helpful people are. The only thing I find disappointing is that it doesn't let you find out facts about your emotions, period, and just growing up until you set up the trial. I really wish it was free. But until then I'm completely fine with just looking at the comments for answers. It's so good to know when Im going to start. It's so scaryaccurate.

This app is decent for tracking and finding out info about different symptoms and things like that. The thing that's making me give it 1 star was the yearly subscription. I had signed up for the free trial and it slipped my mind to turn off the auto renewal. The app basically stole $40 from me. It automatically paid for a yearly subscription after the free trial. I would have been ok with it if it was an auto pay for a month only, but no. An entire year. Reaching customer service is impossible.
