13:11 · 14:10 · 16:8 · 18:6 · 20:4 · 23:1 (OMAD) · 24 h · 36 h · 48 h · custom 12 h⁠–⁠7 days

After each fast

Away from the app

Start and end a fast from Apple Watch or Control Center. Follow it in a widget and on the Lock Screen.

Fair questions

Is fasting safe for me?

Bare Fast is a timer, not medical advice. If you are pregnant or breastfeeding, under 18, have or have had an eating disorder, have diabetes or take medication, talk to your doctor before fasting, even with a daily plan. Before your first long fast, the app shows safety notes.

The health notice has the details. The phases on the ring cite their studies on the sources page.

Where is my data?

Your fasts, moods and notes are stored on your iPhone. There is no account to tie them to you.

The app sends anonymous usage events, such as a fast's length, and crash reports. Privacy lists them.

Why pay for a timer?

You do not have to: the timer is free. Pro pays for the work on the app.

Lifetime is there if you would rather not subscribe.

Do I lose my fasts without Pro?

No. Your fasts stay on your iPhone, with your streak and totals. Free shows the last 3 days in full.

Is there a fasting app without a subscription?

Yes. The Bare Fast timer and daily plans are free, with no time limit. If you want Pro, Lifetime is one payment of $39.99 and never renews.

Does it work on Apple Watch without an account?

Yes. The Apple Watch app is free: start or end a fast and choose a plan on your wrist. There is no account to create, on the watch or the iPhone.
