PulseFast: Fasting Tracker

PulseFast turns a fast into something you can see. Start with one tap and a live ring fills as you go, marking each stage your body moves through — the early hours, fat burning, ketosis. No arithmetic, no spreadsheet, no guessing how far along you are. FASTING THAT FITS YOU Pick a preset — 13, 15, 16, 18, 20, 24, 30, 36, 42, 48, 60 or 72 hours — or set any custom target from 12 hours up to 7 days. PulseFast tracks the fasting window and the eating window that follows, automatically. SEE THE PATTERN Close a fast and attach a note: how hunger went, what you ate, what got in the way. Weeks later those notes turn into something useful — rolling averages, your longest fast, eating-window quality, goals met. A calendar heat-map shows the month at a glance and a weekly chart shows the trend. ALWAYS IN VIEW A Live Activity keeps the countdown on your Lock Screen and in the Dynamic Island. A home screen widget shows current progress. Both keep ticking even if you force-quit the app. MORE THAN A TIMER Log hydration against a daily goal. Track weight toward a target. Read the Learn tab for what actually happens during a fast, and when not to fast. OPTIONAL APPLE HEALTH Grant access and PulseFast shows your steps, walking distance and active energy alongside your fast, and can save the hydration and calories you log back to Health. It is entirely optional — decline it and everything else works exactly the same. YOUR DATA STAYS YOURS No account. No sign-up. No servers. Everything lives on your device, and there are no analytics SDKs, advertising libraries or trackers in the app. Export your full history whenever you want. PulseFast does not endorse or recommend any specific fasting duration. The presets are offered for convenience only. Talk to a healthcare professional about what is safe for you — especially if you are pregnant or breastfeeding, managing diabetes, have a history of eating disorders, or are considering anything beyond 48 hours.
