TrustFast is made by a small studio. If something isn’t working, or you have a question the answers below don’t cover, write to us. A person reads every message.

It helps to include your iPhone and Apple Watch models, their iOS and watchOS versions, and the app version from TrustFast’s Settings.
Questions
Do I need an account?
No. There is no account or sign-in anywhere in TrustFast.
What is free, and what is Plus?
Starting, ending and editing fasts, your schedule, alerts, the Apple Watch app, widgets and the last 7 days of history are free, for good. TrustFast Plus adds all your history and the month and year figures. The yearly plan has a 14-day free trial that starts only when you choose it.
What happens when my trial ends or I cancel?
Nothing is deleted. History older than 7 days stays visible and locked until you subscribe again, and you can always start a fast.
How do I cancel, or restore a purchase?
Cancel in TrustFast under Settings › Subscription, then Manage Plus, or in your Apple Account settings. Restore purchases is on the same Subscription page.
My end-of-window alert didn’t sound.
TrustFast uses the iPhone’s alarms, which need your permission. If you declined it during setup, the app falls back to ordinary notifications, which follow your Focus and silent settings. You can allow alarms again for TrustFast in the iOS Settings app. If it still doesn’t sound, write to us and tell us your iPhone model and iOS version.
Can I use it on Apple Watch without my iPhone?
Yes. You can start, follow and end a fast on the Watch alone. Editing a fast’s times is done on the iPhone. When the two are back in range, each shows what the other did.
I went past my goal, or started late.
That’s fine. When your window ends the fast keeps running, shown as Eat window open, until you end it, so the time you record is the time you fasted. You can edit a fast’s start and end at any time.
Does it work offline? Does it sync to iCloud or Health?
Starting, ending, editing and alerts all work offline. There is no iCloud sync and nothing is written to Health. Your fasts are included in your iPhone backups, so a new iPhone restored from a backup keeps them.
Which schedules does it support?
Daily time-restricted eating: 12:12, 14:10, 16:8, or your own hours, on the days you choose, plus one-off fasts. Alternate-day and 5:2 calendars are not supported.
Is TrustFast medical advice?
TrustFast is a timer, not medical advice. Fasting isn’t right for everyone, including anyone with a history of an eating disorder.
