Fasting Well
Fasting with intention
Free · Designed for iPad. Not verified for macOS.
A fasting tracker that actually feels considered. Track your fast through every metabolic stage, in an app that respects your attention and your privacy.
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.
