A delightful fasting app for iPhone

A fasting app you'll actually enjoy.

Lite is a polished fasting timer that helps you build a healthy habit. Start a fast, see which phase your body is in, and earn coins as your streak grows.

Lite's home screen during a fast: a 14:32 timer inside an orange ring, in the fat burning phase, above a tape of recent fasts

One tap to start. A habit that sticks.

No meal logs, no coaching, no calorie math. Lite counts the hours, keeps your streak, and marks every milestone.

  1. 01

    Start when you stop eating

    Tap once. Forgot? Scroll the start time back to when you actually finished dinner.

  2. 02

    Check in anywhere

    Your fast lives on the Lock Screen, the Dynamic Island, and a widget. Same ring everywhere.

  3. 03

    Finish and keep going

    End the fast and it lands on the tape under the ring. Your streak grows and milestones turn into coins.

Five phases

Know what your body is doing, hour by hour.

Digesting

0 to 4h

Your body runs on energy from your last meal.

Burning sugar

4 to 12h

Insulin falls and your body draws on stored glycogen.

Fat burning

12 to 18h

Glycogen runs low and your body turns to stored fat.

Ketosis

18 to 24h

Your liver turns fat into ketones for fuel.

Deep ketosis

24h and up

Ketones keep rising on longer fasts.

Tap the phase under the timer to see where you are. A 16 hour fast reaches fat burning. Go longer and the next phases stack on.

Look back

Scrub back through every fast.

The tape under the ring is your whole history. Drag it back to any fast to see when it ran and how it went.

Fair questions.

Isn't this just a timer?
It starts as one. Lite also shows which phase you're in, tracks your streak and stats, and marks each milestone with a coin, so the habit sticks.
Are the phases medical advice?
No. They're rough averages from fasting research to show what's likely happening. Everyone's body runs on its own clock, so talk to a doctor before long fasts.
What if I forget to start?
Scroll the start time back to when you finished eating. You can add or edit any past fast from the home screen, too.
Is it free?
Your latest 3 fasts are free. After that it's $3.99 a month, $24.99 a year, or $59.99 once for life. No ads, ever.
Wait, can't I just delete old fasts?
Yep. We built it that way on purpose. Pro is for people who want every fast to stay.

Hi, I'm Maks.

I fast most days. Every app I tried wanted my weight, my meals, and a subscription before it would start a timer. I just wanted to know how long it had been and what that meant.

So I built Lite, and sweated every detail. It turns fasting into a habit you want to keep: a streak to protect, milestones to chase, and a coin for every one you earn.

Start your next fast with one tap.
