A daily body weather forecast
Your cycle phase — period, follicular, ovulation, luteal, PMS — appears as simple weather with a kind tip for the day. Rain means your period; storms mean PMS is near. One glance and you know.
Log your day in 3 seconds
Condition, mood, body signs and flow, all with a few taps. No forms, no clutter, and no banner ads on the logging screen to get in the way.
Period calendar & predictions
Period days, expected period, ovulation day and the fertile window on one calendar. The more cycles you log, the sharper the forecast for your next period and PMS.
Home screen widgets
A weather widget shows today's forecast and period countdown; a quick-log widget records your condition with one tap — without opening the app.
100% offline, no account
There is no server and nothing to sign up for. Your period records, moods and notes exist only on your device, and uninstalling the app erases them completely.
Gentle reminders, never nagging
A morning forecast and an evening check-in, timed your way. On days you already logged, you just get a kind word instead of a nudge.
FAQ
- Is my data uploaded anywhere?
- No. CycleCast has no server and no account system. Period records, moods and notes are stored only on your phone. The only network use is showing ads.
- How accurate are the predictions?
- CycleCast starts from your average cycle length (default 28 days) and refines the forecast as you log more periods. Predictions are estimates to help you plan — not medical advice or contraception.
- Does it show ovulation and fertile days?
- Yes. The calendar marks the estimated ovulation day and fertile window for each cycle, based on your logged periods and cycle length.
- Can I use it discreetly?
- Yes. The app looks like a friendly weather app — a cloud character and forecast, not a clinical period tracker. Light and dark themes are included.
- Is it free?
- Every feature is free. CycleCast is supported by ads, which never appear on the logging screen.
- What languages does it support?
- The app UI is available in 16 languages including English, Korean, Japanese, German, French, Spanish, Portuguese and more.
