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 for the work. Timer, target, and history in one place. Settings live on their own tab and stay out of your way.
• 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 after you close the app, background
it, or restart your phone.
• Never gated. End a fast whenever you want. Your target sets the goal, not the rules. Pass it and the timer keeps counting instead of
stopping at 100%.
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. Change it mid-fast and only the goal moves; your elapsed time is never touched.
FORGOT TO HIT END?
It happens. Set the time you actually stopped. A few taps, no lost fast, no editing gymnastics.
KNOW WHEN YOU'RE DONE
An optional alert tells you the moment you reach your target, so you can put your phone down and get on with your day.
LIGHT OR DARK, YOUR CALL
Follows your system appearance automatically, or pin it to light or dark.
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
Your fasts are stored on your device and nowhere else. No account, no sign-up, no ads, no tracking. The app sends anonymous usage statistics so I can tell which parts are worth improving. Never your fast times, never your history, never anything that identifies you, and you can switch it off any time in Settings.
Esurio is a tracking tool, not medical advice. Talk to a healthcare professional before beginning any fasting or dietary routine.
One tap to start, one number to watch. Fasting without streaks or shame.
