Intermittent fasting timer

The fast,
and nothing else.

One tap to start. Five real metabolic stages. A rest day that doesn’t punish you for taking it. No account, ever.

A fasting ring. The arc is the fast; the gap is the eating window.

The gap is your eating window. Change the schedule and watch it resize.

Stages

Five stages, and the hours behind them.

Every boundary below is the real threshold the app uses. Where the evidence doesn’t support a number, Orbo doesn’t print one.

Restraint

What Orbo doesn’t do.

No food photos

You came for a timer. Pointing a camera at dinner is someone else’s product.

No AI coach

Orbo names the stage you’re in and what it means. It won’t invent numbers it can’t stand behind.

No account to start

Open it, start a fast. Sign in only if you want your history on a second device.

Forgiveness

Built for people who forget.

Forgot to start it? Fix it.

Edit the start. Edit the finish. Add a fast you never logged at all. Your streak heals when you do — most apps make this impossible.

A rest day that costs nothing.

One a week. Take it and your plan extends instead of your streak resetting. It’s free. Charging for that is backwards.

The real thing

Twenty seconds, unedited.

A screen recording of the app running — not a mockup, not a render. The ring you were just playing with is the ring that ships.

Your data

Your fasts stay on your phone.

Orbo works fully offline and keeps your history on the device. Apple Health is optional and one tap to switch off. Signing in exists so your history can follow you to another device — not so anyone can study it.

العربية

Arabic, written — not translated.

Orbo’s Arabic was written first, by someone who reads it. Right-to-left throughout, and dates stay Gregorian instead of a Saudi device silently forcing Hijri on your fasting history. Even the brand mark is pinned so it never mirrors.

Launch

Not on the App Store yet.

It’s built and going through submission. Leave an email and you’ll hear from us exactly once — the day it ships.

One email, then nothing. No list, no sharing.
