What is Cycles?

Cycles is a period and fertility tracker from the Swedish developer Perigee 🌸 A colour-coded view shows your past, current and upcoming periods, and you can log moods, body observations and sex. It predicts your periods, ovulation, PMS and fertile days, and charts help you spot patterns over time. You can invite a partner to follow along; the privacy policy says they see only your cycle phases, not your notes or reminders 💕 Premium adds tailored predictions, partner connection, custom reminders and an insights overview. It runs on iPhone, iPad and Apple Watch, and works without an account, in which case your data stays on your device.
