Frequently asked questions
How do I start a fast?
On the Tracker tab, choose a Shorter or Longer fast (or set a target end date and time), then tap Start Fasting Session.
What is alternate-day fasting?
You alternate between a shorter fast and a longer fast on a repeating cycle, instead of using the same window every day. Set each duration once in Settings and the app alternates them for you.
Can I fix or edit a session I already logged?
Yes. Go to Logs → List and tap Edit Times on a session to correct its start and end times — the duration and completion are recalculated automatically.
Does the Apple Watch stay in sync with my iPhone?
Yes. Start, stop, or adjust a fast on either device and it syncs to the other, including the watch-face complication.
How do I back up my data?
In Settings → Backup & Restore, export your settings and history to a JSON file, and import it on another device.
Is my data private?
Your fasting data stays on your device — there's no account and no sign-in. The app uses Sentry only for anonymous crash reporting. See our privacy policy.
