Free, forever.

Everything you need to fast well is free and stays free. Not a trial. Not “free for now”.

Tap once. Fast.

First fast running within a minute of install. 12:12 to OMAD and custom schedules.

Countdown on your Lock Screen

Live Activity, Dynamic Island, widgets and Apple Watch. You rarely need to open the app.

Forgot to tap? Fix it.

Edit or backdate the start time up to 7 days. No fast is ever discarded.

Stats that are correct

History, streak with freezes, averages that are unit-tested — not guessed.

Eating-window mode

See when your window closes instead of counting up. Free, switchable.

Switch without losing a day

Import your history from other fasting apps. Back up and restore to a file — free.

One honest price.

Fastbloom Plus adds the Apple Watch app, every widget, deeper stats, iCloud sync, export and themes. Try it free for 14 days — no card, nothing to cancel. If you do nothing, the app simply stays free.

The price is the price. It never changes after the first year, and we never ask again once you’ve said no.

Is it really free?

Yes. Timer, schedules, history, reminders and the Lock Screen countdown are free for as long as the app exists. Plus is optional.

Do I need an account?

No. Your data stays on your iPhone. iCloud sync (Plus) uses your own private iCloud.

What does “Try Plus” mean?

14 days of Plus with no card and nothing to cancel. When it ends, the app stays free. Nothing converts automatically.

Can I bring my history from another app?

Yes — import a CSV or backup from Zero, FastHabit, Easy Fast or any app with an export.

What can I drink during a fast?

Water, black coffee and unsweetened tea are the usual answer. Anything with calories ends the fast. This is general information, not medical advice.

How do I cancel Plus?

iPhone Settings → your name → Subscriptions. Cancelling keeps Plus until the end of the paid period.

Does Fastbloom use my Health data?

Only if you allow it, Fastbloom writes the water you log to Apple Health. It never reads your Health data and never sends it anywhere.

How do I delete my data?

Delete the app, or use Settings → Delete all my data inside Fastbloom. There is no account to close.

Fastbloom is not medical advice. If you’re under 18, pregnant or breastfeeding, have a history of disordered eating, or take medication that affects blood sugar, talk to a doctor before fasting.
