Esurio | Intermittent Fasting

Fasting, stripped to the essential. Tap to start, tap to end, and watch one live number climb toward your target. No streaks, no shame, no clutter.

Esurio is intermittent fasting stripped to the essential: tap to start, tap to end, and watch one live number climb toward your target. No streaks, no shame, no clutter — just the fast you're in and the ones you've finished.

ONE BUTTON. ONE NUMBER. Start a fast with a single tap and a live timer counts up toward your goal. Tap again to end it. That's the whole app.

BUILT AROUND FOUR IDEAS • One screen — timer, target, and history all in one place. No menus to dig through. • Green means live — the app lights up only while you're actually fasting. • Honest time — every number is calculated from real timestamps, so your elapsed time stays accurate even after you close the app. • Never gated — end a fast whenever you want. Your target sets the goal, not the rules.

CHOOSE YOUR TARGET 16 hours by default, plus 18, 20, and 24-hour presets — or set a custom target from 1 to 48 hours to fit the way you fast.

YOUR HISTORY, AT A GLANCE Every completed fast is saved with its start, end, and duration. Fasts that hit your target are marked, so you can see your consistency without a single streak counter.

PRIVATE BY DESIGN Esurio stores everything on your device. No account, no sign-up, no tracking — nothing is sent anywhere. Your fasts are yours.

Esurio is a tracking tool, not medical advice. Talk to a healthcare professional before beginning any fasting or dietary routine.
