Nistis: Fasting Timer

A fasting timer. That's it. Free to use, no account, no ads, no AI coach, no subscription required — upgrade once and keep it forever. Fix a forgotten fast in two taps. Your data stays on your device and exports any time.

THE TIMER Pick a preset — 16:8, 18:6, 20:4, OMAD, 5:2 — or set a custom fast. One big ring shows elapsed, remaining, or percent; tap to switch. Started fasting before you opened the app? Adjust the start time mid-fast. Ending early or late? The end time is editable too. No lectures either way.

YOUR HISTORY IS YOURS TO EDIT Every fasting app makes logging mistakes. Nistis is the one that lets you fix them: any fast, any field, any time — including days you forgot entirely. Tap an empty day, add the fast, done. Streaks and stats recompute instantly. No punishment screens.

STAGES, NOT SERMONS A simple timeline shows the stages commonly associated with fasting — digesting, fat burning, ketosis ramp — with honest, hedged language and no medical claims.

FREE MEANS FREE The timer, every preset, unlimited history with full editing, streaks, stats, notifications, and a home-screen widget. Free forever — in writing. Whatever ships free stays free.

NISTIS PRO — PAY ONCE IF YOU WANT MORE • Apple Watch app with complications — start and end from your wrist • Live Activity and Dynamic Island — your fast on the lock screen • Every widget style, including lock-screen widgets • Apple Health sync for weight and water • Advanced stats: trends, completion rate, weight overlay • Import from other fasting apps (first import free) and export any time

$2.99/month, $14.99/year, or $29.99 once — yours for life. Other fasting apps charge $69.99 every year for less.

PRIVATE BY ARCHITECTURE No account. No ads. No tracking SDKs. Works completely offline; optional iCloud sync uses your private iCloud, which we can't read. The only thing the app ever phones is Apple's purchase system. Check our App Store privacy label against any other fasting app — that's the whole pitch.

Nistis — Greek νήστις, "the one who fasts." Pronounced NISS-tis.
