Common Questions
Does FAST40 sync with Apple Health?
Yes. With your permission, FAST40 can read weight data from Apple Health and write fasting sessions back to it.
Is the GLP-1 log required?
No. The GLP-1 dose logger is completely optional. You can use FAST40 as a standard fasting tracker without it.
What happens if I break my fast early?
Tap End Fast early. Your session is logged at its actual duration. Your streak resets only if you go a full day without completing a qualifying fast.
How do I cancel my subscription?
Open the App Store app, tap your profile, go to Subscriptions, and cancel FAST40 from there.
