Track every fast.
Nothing else.
A minimalist intermittent fasting tracker for iOS. One calendar. One streak. No accounts, no ads, no analytics.
Fasting apps got bloated.
We built the opposite.
Ever. Not in the free tier. Not anywhere.
No email, no password, no sign-in screen. Just open and start.
One timer. One calendar. No coach, no community, no gimmicks.
Every feature earns its place.
Six screens. Zero fluff.A year of discipline, at a glance.
Every day is a cell. Intensity follows hours fasted. Keep the line going.
Persistent. Live Activity. Dynamic Island.
Your timer survives reboots, app closes, and low battery. Milestones at 4h, 8h, 12h, 16h, 20h.
Ten themes. One discipline.
Classic is free. Nine Pro themes — Forest, Ocean, Sunset, Fire, Cherry, Mint, Passion, Sunshine, Night.
Log a fast in under five seconds.
Quick-select chips, auto-calculated durations, midnight crossings handled. Mood and weight optional.
"Discipline is choosing between what you want now and what you want most."
A trend line, not a guilt trip.
Optional weight tracking. No streaks-you-lose notifications. No shaming copy. Just the line.
Earn them quietly.
Unlock milestones at 7, 30, 50, 100 days. No emoji explosions. No confetti.

Short answers.
Do I need an account?+
No. No email, no password, no sign-in. Open the app and start your first fast.
What happens if I delete the app?+
Your iCloud data stays. Reinstall on any Apple device signed into the same Apple ID and your streak is there.
Can I export my data?+
Yes. CSV export of your entire history is available on both Free and Pro, any time.
Is there an Android version?+
No. Streak Fast is iOS-only and staying that way. Native SwiftUI, Live Activities, Dynamic Island — it only works because we didn't try to ship it everywhere.
Do you track me?+
No analytics, no ad SDK, no third-party trackers. We can't see your data because your data never touches our infrastructure.
What devices sync?+
Any Apple device signed into your Apple ID with iCloud enabled. iPhone, iPad, Mac (when the Mac version ships).
