Ahonui vs · Zero
The Zero alternative that makes you finish the fast
Zero times your fast. Ahonui times it too, and keeps the apps you pick blocked until the fast is done.

If you're looking for a Zero alternative, the timer probably isn't the problem. Zero's timer is good: one tap and it starts counting.
The problem is hour 14 of 16, when the timer is still going and DoorDash is one tap away.
Zero can tell you that you broke your fast. It can't stop you from breaking it.
Two hours to go. The zip stays shut.
A timer can't stop you
Zero is a good tracker: a free fasting timer, streaks, weekly trends and articles. The paid plan adds photo meal logging, a protein score and water tracking.
But it never gets between you and the food. It only keeps a record, and ending early just costs you a streak after the fact.
Ahonui puts the fast between you and the app
Still fasting, no DoorDash.
You set the fast and pick the apps that wait for it. They stay blocked until the fast is done.
- Food delivery apps, if that's how your fasts usually end.
- Instagram or YouTube, if you'd rather earn your evening scroll.
- A fast can run past midnight, and the apps are unblocked when the timer ends.
It's the same kind of timer. The difference is that something's riding on it.
More than the fast
Ahonui does the same for water, exercise, sleep, weigh-ins and meditation, and it logs meals too. Your fast and your morning workout can live in one app.

Which one is for you
If you finish your fasts and just want a record, stay with Zero. The timer is free and it's good. If you're on Android, Zero is there and we aren't.
If your fasts keep ending in the same app, a record won't fix that. Block the app until the fast is done.
