FastClear vs Zero, Fastic and BodyFast

Questions
Frequently asked
Is FastClear free?
Yes — FastClear is free to download and the core timer is free to use. An optional subscription unlocks advanced protocols and extended history.
What's the best app for private intermittent fasting?
FastClear is built specifically for people who want a private fasting timer: it has no account, no analytics and no trackers, and every fast is stored on your own device rather than on a company server.
Does FastClear need an internet connection?
No. FastClear works fully offline. A connection is only used by Apple to manage an optional subscription.
Does FastClear share my fasting data?
No. Your fasting history never leaves your device unless you choose to write completed fasts to Apple Health, which stays under your control in the Health app.
Does FastClear support 16:8 and OMAD?
Yes. FastClear supports 16:8, 18:6, 20:4, OMAD and fully custom fasting windows.
How is FastClear different from Zero, Fastic or BodyFast?
FastClear is a fasting timer only, built for privacy: its App Store privacy label is "Data Not Collected", it has no ads and no account, and its in-app purchases are listed from $3.99 to $24.99. Zero, Fastic and BodyFast go further with food and calorie tracking (and an Apple Watch app for Zero), but according to their App Store listings they collect data linked to your identity, and Fastic and BodyFast also contain ads and use data to track you.
