Your cycle, honestly predicted.
Ebb learns the length of your cycles and shows the next period as a window, give or take the days it is actually unsure about. No false precision, no guesswork dressed up as certainty.
Everything stays on your phone. No account, no upload, no analytics. App lock and discreet mode are there when you want the app to keep quiet about what it is.
What it does
- A cycle wheel with the current phase, the fertile window estimate and the prediction window.
- A five second log: flow, symptoms, moods, sleep, a note.
- Insights that need real data: cycle history, symptom patterns per phase, a regularity trend.
- Reminders before your period, on the expected day, and for logging.
- CSV, calendar and PDF export, all on an explicit tap.
