The Clue app offers period, PMS, ovulation and fertile window predictions.
For more precise fertile day predictions, we also have Clue Conceive mode, which uses a clinically-validated algorithm for its calculations.
With features in the Analysis Tab, you can also learn your patterns to better anticipate what to expect each cycle. By analyzing your tracking data, Clue gives you personalized insights into what’s common for you. You’ll get a deeper understanding of your cycle statistics, period flow, cramps, feelings, sleep, and more.
