CycleCast: Period, PMS Tracker

See your cycle like the weather.

CycleCast is a period tracker that turns your menstrual cycle into a gentle daily forecast. Rainy days, sunny days, stormy PMS days — open the app (or just glance at the widget) and instantly know what your body is up to today.

No account. No server. 100% offline.
Your period records, moods, and notes are stored only on your phone. We never see them — there is nothing to sign up for and nothing to leak.

• Log your day in 3 seconds — condition, mood, body signs, and flow with a few taps. No forms, no clutter
• Period calendar — period days, expected period, ovulation day, and fertile window at a glance

WHY WOMEN CHOOSE CYCLECAST

Most period tracker apps want an account, a subscription, or your data. CycleCast wants none of that. It is a simple period calendar and PMS tracker that respects your privacy: everything stays on your device, and uninstalling the app removes it completely.

Whether you want a period diary, an ovulation and fertile window calendar, or just a heads-up before PMS hits — CycleCast keeps it simple, warm, and yours.

Download CycleCast and read your body's rhythm like tomorrow's weather.
