FastPure

FastPure is a no-nonsense intermittent fasting timer: ultra-light and 100% offline. One purchase, for life. No account, no ads, no data ever leaving your phone. Intermittent fasting (16:8, 18:6, OMAD…) doesn't need a €40-70/year subscription, an account, or cloud syncing of your eating habits. FastPure does one thing, perfectly: track your fasting and eating windows with absolute clarity — then leave you alone. PAY ONCE. THAT'S IT. • A single lifetime purchase. No subscription, ever. • No account, no sign-up. • No data sent to any server. Everything stays on device. FEATURES • Ready-made protocols: 14:10, 16:8, 18:6, 20:4, OMAD (23:1) + a custom free mode. • Large progress panel: elapsed time, remaining time and current phase at a glance. One-tap start/stop. • Educational metabolic tracker: digestion, estimated ketosis switch (12-16 h), estimated autophagy peak (16 h+). Informative, never medical advice. • Retroactive start-time adjustment: forgot to start the timer? Fix it in one gesture. • Smart local notifications: fasting end and optional milestones. 100% local, no server. • Local history & streaks: current streak, longest streak, total fasts, average duration and a weekly chart. • Widgets & Live Activity (iOS): countdown on your home screen, lock screen and Dynamic Island. • Local export: save your history to a shareable CSV file, no cloud involved. • Minimalist by design: light & dark themes, tiny battery footprint, multilingual interface (7 languages) matching your device, zero aggressive gamification. FREE or PRO The free version offers the 16:8 protocol with no time limit and the local end-of-fast alert. The one-time FastPure Pro purchase unlocks all other protocols (14:10, 18:6, 20:4, OMAD, Custom), full history and charts, CSV export and metabolic milestone notifications (fat burning, ketosis, autophagy). PRIVACY FIRST Where the whole market runs on subscriptions and the cloud, FastPure makes privacy and a one-time purchase its core promise. Your fasting data is yours and never leaves your phone.
