One ring

One ring.
Right now.

See where you are in your fasting window with just an arc and a number.

Open. Tap.
Close.

That’s the whole routine. The rest can wait.

Markers at
4, 8, 12, 16 hours.

Landmarks line up quietly along the ring. No confetti, no nagging.

And then,
mealtime.

When your fast ends, the time you kept stays right there.

Everywhere

On your wrist. On your Lock Screen.
In your voice.

The same ring on iPhone, iPad and Apple Watch.

iPad

Made for iPad, too.

On the bigger screen, the layout opens into two columns. Same ring, same feel.

Apple Watch

A glance. A tap.

The ring and the start and end buttons, right on your wrist.

Widgets

On your Home Screen and Lock Screen.

Your status and time left, without opening the app.

Live Activity

The last 8 hours,
on your Lock Screen.

The time until you can eat shows on the Lock Screen and in the Dynamic Island.

Siri and Shortcuts

Say it, or shortcut it.

Start or end a fast, or log your weight, just by asking.

Records

Keep only what you want.

All of it is optional. The ring works without any of it.

Food

Suggestions for items can come from a photo, on your device. Photos are never saved.

Weight and mood

Records stay on this device. Writing to Health happens only if you turn it on.

Weekly summary

On supported devices, Apple Intelligence on your device puts your week into gentle words. Your data never leaves it.

Privacy

Your records stay
on your device.

No accounts. No sharing. The developer doesn’t receive your health records.
