Live on your Lock Screen & Dynamic Island
A fasting timer that gets out of your way
Open the app, tap Start, done. Super Fasting Tracker does the rest — tracking, reminding, and motivating you all the way to your goal.
One-Tap Timer & Plans
Popular schedules built in — 13:11, 14:10, 16:8, 18:6, 20:4 and OMAD — or create a fully custom fast from 4 to 48 hours with Pro. Forgot to tap? Edit your start time any time.
Real-Time Fasting Zones
Follow your body from Anabolic through Fat Burning to Deep Ketosis, with clear explanations of what's happening at every stage.
Live Activity & Dynamic Island
Your timer, progress and current zone live on the Lock Screen and Dynamic Island — no need to open the app to check in.
Streaks, Stats & Badges
Streaks with Duolingo-style freezes, weekly recaps you can share, a calendar heatmap, 7-day charts and 19 badges to earn.
Weight & Water Tracking
Log weight and water in a tap, see your trends, and sync both ways with Apple Health — always under your control.
Widgets, Siri & Controls
Interactive Home Screen and Lock Screen widgets, Control Center toggle, and Siri shortcuts — start or end a fast without opening the app.
See what your body is doing, hour by hour
From the moment you start, the app shows which metabolic stage you're in and what it means — so every hour of your fast feels like progress.
🍴 Anabolic
Digesting and absorbing your last meal.
📉 Catabolic
Blood sugar dips — stored energy starts being used.
🔥 Fat Burning
Glycogen runs low — fat becomes a main fuel.
⚡ Ketosis
Ketone production ramps up.
✨ Deep Ketosis
Extended fasting territory.
Hour marks are general estimates and vary from body to body — the app explains each stage without medical claims.
Three taps to a better habit
No setup marathon, no account creation — you'll be fasting within a minute of downloading.
Pick your plan
Choose 16:8, 18:6, OMAD or another preset — or build your own custom fast with Pro.
Start your fast
One tap and the ring starts filling. Forgot to start it earlier? Just edit the start time.
Follow along anywhere
Track progress on your Lock Screen, in widgets or with notifications, then finish your fast and watch your streak grow.
No account. No ads. Your data stays yours.
Super Fasting Tracker works entirely without sign-up. Your fasting history, weight and water logs are stored on your device, and Apple Health syncing is optional and fully under your control. There are no ads in the app — and your health data is never used for advertising, period.
Go further with Pro
The free app is a complete fasting timer — starting a fast is never locked or limited. Super Fasting Tracker Pro adds custom plans from 4 to 48 hours, mood & notes on every fast, your full history beyond 30 days, and CSV export. Pro is available as an auto-renewing subscription (with a free trial when offered) or a one-time lifetime purchase, and you can manage or cancel it any time. See the subscription terms.
Super Fasting Tracker is a wellness tool, not a medical device, and it doesn't provide medical advice. Talk to your physician before starting a fasting program — especially if you are pregnant or breastfeeding, under 18, have diabetes, low blood pressure or a history of eating disorders, or take medication. Stop fasting and seek medical advice if you feel unwell.
