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. No forced trial to open the app, no hidden charges. PeriodCast Plus is an optional auto-renewing subscription that unlocks your full cycle history — view every logged period, add past dates, and correct mistakes. Clearly priced, cancel anytime. Subscription: auto-renews unless canceled at least 24 hours before the current period ends; payment is charged to your Apple ID at confirmation; manage or cancel in your App Store settings.
