Fasting Hours Tracker

Intermittent fasting tracker online no app — tap each hour and watch your fast build up. Use the free Fasting Hours Tracker below — enter your values and get instant results, right in your browser. Logic: a simple tally counter starting at 0 with step 1. Hours fasted = number of taps. Common targets: 14:10 or 16:8 (fast:feed windows); reaching the target number means the fast is complete.

How to use the Fasting Hours Tracker

Intermittent fasting lives or dies on one number: hours since your last meal. Most trackers demand an app install, an account and notifications you never asked for. This intermittent fasting tracker online needs none of that — no app, no signup. Start your fast, tap + once per hour (or at each check-in), and watch your hour count climb toward your 14, 16 or 18-hour goal right in the browser.

  1. When your fast begins (after your last meal), open the tracker.
  2. Tap the + button once for each hour that passes — or tap in batches at check-ins.
  3. Watch the big number climb toward your goal: 14, 16 or 18 hours.
  4. If you tap too many times, use the − button to correct.
  5. When you break the fast, note your total, then hit Reset for the next fast.

Formula

Logic: a simple tally counter starting at 0 with step 1. Hours fasted = number of taps. Common targets: 14:10 or 16:8 (fast:feed windows); reaching the target number means the fast is complete.

Worked example

Last meal at 9 PM, goal 16 hours. Tap + at each hour — by 1 PM next day the counter reads 16. You hit a 16:8 fast with zero apps installed. Hit Reset tonight and start the next one the same way.
