About this app

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.

šŸ”‘ Key features

ā±ļø 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.

šŸŽÆ 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.

šŸ”„ 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.

āš–ļø 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.

šŸ“± 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.

šŸ’” 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.

šŸš€ Download Simple Fast today and take control of your intermittent fasting journey — privately, simply, and beautifully.

Note: Simple Fast is a time-tracking tool, not medical advice. Consult a healthcare professional before changing your eating patterns.
