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.
