Simple Fast — the fasting tracker that respects your privacy.
A clean, offline-first intermittent fasting tracker that helps you build a consistent habit. One tap starts your fast, a beautiful ring counts you down, and an honest streak rewards real effort — not early taps. No account, no cloud, no clutter.
🔑 Key features
⏱️ Live fasting timer: Elapsed and remaining time inside a circular progress ring that shifts from neon green to amber as your goal approaches. The eating-window indicator shows exactly where you are in your day.
🎯 Four fasting protocols: Gentle 12:12 for beginners, Leangains 16:8 for the popular approach, Warrior 18:6 for intermediates, and Intense 20:4 for veterans. Switch any time — your fasting tracker adapts to your routine.
🌸 Mandala weekly chart: A unique 7-segment ring that turns your consistency into a glanceable picture — green for completed days, amber for in progress, red for missed. No other fasting tracker visualizes your week this way.
🔥 Honest streaks: Current and longest streaks, increased only when your actual fasting duration meets the plan. No fake wins — your fasting tracker tells the truth so your habit stays real.
⚖️ Weight log & BMI gauge: Track weight in kg or lb with trend charts across 7-day, 30-day, 90-day, and all-time views. A half-circular BMI gauge with WHO category bands (Underweight, Normal, Overweight, Obese) keeps the big picture in view.
📱 Home Screen Widget: See your weekly fasting report — completed days, current streak, and average fasting hours — right on your home screen. Tap to jump straight into the app.
💡 Why choose Simple Fast?
Most fasting apps want your account, your cloud, and your data. Simple Fast is built differently — it's a fasting tracker that stays out of your business. Every session, weight log, and streak is stored in a local database on your own device. There is no server, no sign-up, and no data shared with third parties. You fast in complete privacy, the way health tracking should work.
The interface is calm and premium — a deep forest-green canvas with a single neon-green accent, Lexend typography, and Material 3 spacing inspired by Apple Health, Whoop, and Oura. A fasting tracker that feels like a wellness companion, not a cluttered dashboard.
🚀 Download Simple Fast today and take control of your intermittent fasting journey — privately, simply, and beautifully.
