My Days - Period and Ovulation Calculator is an app to help predict your period, ovulation, and phases of fertility – all from your Android device, where you can consult it at any time.

The program includes a good handful of very useful features. From the calendar you can mark the days you take your birth control or have had sex, or simply jot down a series of notes.

To help you stay on top of all the factors so important to you as a woman, the app comes with no less than four widgets that you can configure as desired so you can always remember which day you start your period.
