## Description

**Clue: Period & Cycle Tracker** is a science-based menstrual health app for tracking periods, ovulation, fertility, pregnancy, symptoms, and cycle patterns. Use the calendar to predict upcoming periods and fertile days, log more than 200 factors—including mood, sleep, energy, and sex drive—and receive cycle phase and birth control reminders.

Clue also offers clinically validated fertility predictions, basal body temperature tracking, pregnancy guidance, perimenopause and irregular-period tools, and support for monitoring PCOS or endometriosis symptoms. Connect compatible wearables such as Oura, WHOOP, and Fitbit for deeper health insights. Explore expert-written educational content while keeping your data protected under strict EU privacy laws. Clue predictions should not be used as contraception.
