About this app
A clearer way to follow your fast—built around your time, not your data. Simple Fasting App gives you a calm, focused place to plan a fast, follow your progress, and understand your routine. No ads, subscriptions, in-app purchases, or account required. CHOOSE YOUR RHYTHM Choose 12:12, 16:8, 18:6, 20:4, or a 24-hour fast—or set a custom duration. Adjust your start time when your day changes, and finish a fast early whenever you need to. FOLLOW EVERY FAST See elapsed and remaining time, start and end times, your current plan, and completion status in one clear live view. An optional reminder can let you know when your planned fasting window ends. EXPLORE FASTING INSIGHTS Choose whether to see time-based fasting stage estimates as your fast progresses. Each stage includes clear context so you can understand what the estimate means—and what it does not. UNDERSTAND YOUR ROUTINE Review completed sessions, total fasts, average duration, your longest fast, weekly averages, and monthly patterns. Open any day to see its timeline and session details. KEEP PROGRESS IN VIEW Follow an active fast beyond the app with Home Screen widgets, Live Activities, and Dynamic Island on supported iPhone models. MAKE IT YOURS Choose light, dark, or system appearance and select an accent color that suits you. PRIVATE BY DESIGN No sign-up. No account. No ads. No subscriptions. No in-app purchases. Your fasting history stays on your device, and Simple Fasting App does not collect or sell your data. Fasting stages are general estimates based on elapsed time. They do not measure your individual metabolic response and are not medical advice. Fast with clarity, at your own pace.
