Period Tracker: Ovulation App

Bloomtide is a private period tracker and ovulation tracker with a clear period calendar, honest predictions and no account. Everything you log stays on your phone.

Know when your next period is likely to start, see your fertile window and estimated ovulation day, and understand your cycle phases, symptoms and moods. When your cycles vary, Bloomtide shows a date range instead of pretending to know the exact day.

WHY BLOOMTIDE
- Private by design: no account, no cloud, no selling or sharing of your health data. Cycle data is stored only on your phone.
- Honest free tier: period tracking, predictions, the period calendar, reminders, CSV export, backups and every article are free.
- Made for real cycles: works with regular and irregular cycles, long cycles and PCOS, the first years of periods and perimenopause.
- No ads on your Today screen, calendar or daily log.

OVULATION TRACKER AND FERTILE WINDOW
- Fertile window and ovulation estimates with a daily chance of pregnancy (low, medium, high)
