Fasting Well is a beautiful, science-grounded intermittent fasting tracker. Designed for the moments your fast actually happens — at home, in transit, before bed — with the kind of polish you'd expect from an app you open every day. EVERY FAST IS A JOURNEY A fast isn't a single state — it's a sequence. Anabolic. Catabolic. Fat-burning. Ketosis. Deep ketosis. Fasting Well shows you exactly where you are in that journey, with stage-aware visuals and a quiet narration of what's happening inside. WHAT YOU GET (FREE) • Live timer with the ring you'll want to watch • Six built-in plans: 16:8, 18:6, 20:4, OMAD, 24h, 36h • Stage-aware progress: see Anabolic → Ketosis unfold • Notifications when you cross a stage or hit your goal • Journal of your last 30 days with a weekly chart • Five long-form science articles, beautifully illustrated • Calendar heatmap of recent activity • Dark and light themes that look right on every screen WHY ANOTHER FASTING APP Because the popular ones either gutted their free tier or never felt like apps you'd open without a reason. Fasting Well is built to be the home screen icon you actually like seeing. PRIVACY-FIRST Your fasts and weight data stay on your device — no account, no cloud sync, no servers we own. To make the app better we collect anonymous usage signals (e.g. "a fast was started on the 18:6 plan" or "an article was opened") through PostHog. These contain no personally identifying information and can be turned off entirely in Settings → Privacy. SCIENCE-BACKED, NOT WELLNESS-HYPE Built on peer-reviewed fasting research. No talk of "detox." No supplements to sell. Just the metabolic story your body is actually telling. FASTING WELL PRO Go deeper with Pro: build custom fasting protocols, log your weight and watch the trend, unlock advanced statistics (12-week heatmap, completion rate, best streak), share beautiful fast cards, and pick from every accent color. Pro is a monthly or annual subscription, or a one-time lifetime purchase — and the core tracker stays free forever. QUESTIONS, FEEDBACK hello@fastingwell.app We're a small team.

WHAT YOU GET - Your fast, right on the Lock Screen, in real time - A widget for the Lock Screen and the Home Screen - Fasting and eating that switch automatically at the right time - Gentle reminders when a fasting or eating window begins - Set it once and let it repeat every day HOW IT WORKS Pick when your fasting starts and how long it lasts. Your eating window fills in the rest. Add the widget to your Lock Screen and you are done. It quietly follows your schedule from then on. MADE SIMPLE ON PURPOSE No food logging, no charts to keep up with, no clutter. One glance tells you where you are in your day. PRO Unlock everything with a subscription.
