Free fasting app · iOS and Android

An intermittent fasting app without the drama.

A fasting timer, your journal and short reads. Clear timing without rigid rules: you decide when to start and when to finish. Blimbi counts.

  • Free
  • No ads
  • Sign in with Apple or Google
Blimbi iOS timer while fasting: 12 h 0 min elapsed of a 16 h target, 4 h left, Metabolic switch stage guide, start Mon 8:38 PM and planned end Tue 12:38 PM, End fast button

You start it. You end it.Reaching the expected time never ends a fast for you.

Inside the app

A fasting tracker with no pressure.

Two states, a journal that forgives, and guides that stay honest. No streaks to break, no guilt.

  • Two states. You decide when to switch.

    Fasting counts from your start. Eating counts from the end of your last fast. Reaching the expected time does not change your state.

    Blimbi in Eating mode: 4 h 30 min since the last fast ended, suggested eating window 8 h, Start fast now button, and start and end times of the last fast

  • Your month, at a glance.

    Every fast lands in your journal. Edit a time you forgot, review a partial day, export to CSV. Guilt-free.

  • Stages explained, no hype.

    Short, time-based guides. Never a reading of ketosis, glucose or anything inside your body.

  • Goal reached. No contest.

    You reached your target. Going longer is not a competition.

FAQ

Questions about the Blimbi app.

Still curious? Contact support

Is Blimbi free?

Yes. The timer, safety information, basic journal, reminders and CSV export are free, with no ads. Blimbi Plus is optional; check your store's price and terms before buying.

Do I need an account?

Yes, on new installs: you sign in with Apple or Google, and your journal is end-to-end encrypted so Blimbi cannot read it. If you installed Blimbi before version 2.4.0, you can keep using it without an account.

Does Blimbi start or end a fast automatically?

No. You choose when to start and finish. The expected time is a reference; reaching it does not end your fast or start the next one.

Is it on Android? What about widgets?

Yes: Blimbi is on the App Store and Google Play, with widgets on iOS and Android. Live Activities, Shortcuts and Apple Watch are iOS features. Compatibility depends on your device and system.

What does Blimbi Plus include?

Custom weekly and per-day rhythms, a note from your professional that you add yourself, a reviewable assisted draft, deeper analysis, personalization and, on iOS, PDF reports with custom periods and sections. The timer, safety information, basic journal, reminders and CSV export stay free.

Do stages show what is happening in my body?

No. They are a time-based educational guide, not a measurement of ketosis, autophagy, glucose or other processes. Blimbi is not a medical device and does not replace professional care.

Fasting, no drama.

You decide. Blimbi counts. Free on iPhone and Android.
