You only need this one!

I have tried out a lot of cycle apps for a lot of reasons - period reminders, to try to get pregnant, to try to NOT get pregnant- but this is the best app, hands down, ever, the end! I love the design, the education, the reminders, and the customization capability! I have even raved about this app to friends!
