PeriodCast: Period Tracker

PeriodCast predicts your period and fertile window from your own logged cycles — and the prediction actually adapts as your body changes, instead of staying stuck on a fixed 28-day guess. WHAT IT DOES • Adaptive predictions: recent cycles are weighted more heavily, so when your cycle shifts, your next-period and fertile-window forecasts shift with it. • Cycle wheel: see your whole cycle at a glance — period days, fertile window and ovulation — on one clear visual ring. • Fertile & ovulation window: know your predicted fertile days and estimated ovulation date, computed from your data. • Cycle insights: your average cycle length, how regular you are, prediction confidence, and a history chart that shows the adaptive engine at work. • Phase guide: tap your cycle for a plain-language explanation of the current phase and what to expect, with links to medical sources (NHS, NIH, BMJ). • Cycle history: view every period you've logged, add a date you forgot, and delete a mis-logged day so your predictions stay accurate. • Discreet reminders (optional, off by default): a heads-up before your next period and before your fertile window begins — automatically updated every time you log a new period. PRIVATE BY DESIGN Everything is computed on your device. No account to create, no cloud sync of your cycle data. HONEST BY DESIGN Core tracking is free.
