Clue is a period, ovulation, and pregnancy tracker with a clear mission: to empower you to know your body, through all stages of life, and whatever your reproductive decisions may be. Trust and transparency is at the core of everything we do.

The feature is simple. When you enter your period date, the next period date is predicted and displayed on the calendar. It doesn't show Ads, columns, and the best time to lose weight. It simply tells you when your period is due.
