# Clue

Period and cycle tracker for iOS and Android with science-based predictions and no pink design.

Clue is a cycle tracking app that logs periods, symptoms, moods and basal body temperature, then predicts periods and fertile windows. It also offers modes for pregnancy tracking and perimenopause. Clue is a tracking and education tool; it is not a contraceptive or a fertility diagnostic.

Price: Free; Clue Plus subscription adds features. Site: https://helloclue.com/.
