## What is TrustFast?

TrustFast is an intermittent fasting timer that stays out of your way. Set your window once, and it tells you when your fast starts and when you can eat again.

A TIMER YOU CAN TRUST
• Alarms when your window starts and ends, so you don't have to watch the clock
• Today leads with the one thing that matters: the time your window turns
• A Live Activity on the Lock Screen and in the Dynamic Island shows when you can eat

FITS YOUR LIFE
• 16:8, 14:10, 12:12 or your own hours, on the days you choose
• Late dinner? Edit the start, and the rest follows
• Ended early or skipped a night? It still counts. No streaks to break

ON YOUR WRIST
• The Apple Watch app starts and ends a fast on its own, even with your phone away
• Home Screen widgets show your window at a glance
• Start a fast from Shortcuts

PRIVATE BY DESIGN
• No account, no sign-up
• Your fasting data stays on your iPhone and Apple Watch
• No ads

FREE, WITH PLUS IF YOU WANT MORE
Everything above is free, along with your last 7 days of history. TrustFast Plus adds all your history and the month and year figures, monthly or yearly, with a 14-day free trial on the yearly plan. If Plus ends, nothing is deleted: older days stay visible and locked, and starting a fast is always free.

TrustFast is a timer, not medical advice. Fasting isn't right for everyone, including anyone with a history of an eating disorder.
