Clue is such an invaluable app! As someone with PCOS and other health conditions that contribute to painful and irregular cycles, Clue has helped me to see patterns in my cycle.

This app is almost scary with how accurate it is in prediction of ovulation and menstruation times. I'd give 10 stars if I could.
