The intermittent fasting timer that shows which fasting phase you have likely reached, from fat burning lipolysis to ketosis and autophagy, based on how long you have fasted. Ad free. No account required. Most fasting apps give you a countdown clock and a streak to protect. Intermittent does something different. It maps your hours fasted to the phases research describes, and explains the science behind each one with cited primary sources, not marketing copy. If you have ever wondered how to track fasting properly, or what is likely happening during a fast, this is the fasting tracker built for that question. WHY FASTING WORKS Intermittent fasting works because of what happens between meals, not just the absence of food. As your fast progresses, your body moves through distinct phases: burning through glucose reserves, shifting into fat burning lipolysis, entering ketosis, and eventually triggering autophagy, the cellular repair process linked to longevity and metabolic health. Understanding these transitions is what separates intentional fasting from guesswork. Intermittent maps every stage so your goals are grounded in biology, not motivation. KEY FEATURES PHASE AWARE FASTING TIMER A live timer that maps your fast to six phases: Fed, Early Fasting, Lipolysis, Ketosis, Autophagy, and Deep Fast. Each phase links to a free science article with primary sources cited. EVERY FASTING PROTOCOL, ONE APP Supports 12:12, 14:10, 16:8, 18:6, 20:4, OMAD (One Meal A Day), 36 hour, 48 hour, and 72 hour fasts. FREE FASTING SCIENCE LIBRARY A full library of fasting articles covering intermittent fasting, ketosis, autophagy, insulin response, and more. No subscription. No account. No paywall. SMART HYDRATION TARGET A science backed hydration goal that adapts to your weight, sex, age, and fasting duration. WEIGHT AND PROGRESS TRACKING Log your weight after each fast and track trends over time. Includes streak heatmap, phase reach history, and estimated fat vs glucose energy usage. PRIVATE CIRCLE AND END OF FAST REFLECTION Share your fast with a small private group. Applause only responses. No comparison. No gamification. HOME SCREEN WIDGET AND CROSS DEVICE SYNC Keep your fasting timer visible with a home screen widget. Your data syncs across devices privately without third party trackers. EATING WINDOW, REMINDERS AND RECAPS See your eating window after each fast, with an optional heads-up before it closes. Set your usual start time for a gentle reminder. Look back on each month and year with a recap you can share. WHO IT IS FOR Intermittent is built for adults who want to understand fasting, not be coached through it. If you follow research on metabolic health, read about longevity, or want a fasting routine grounded in biology rather than points or streaks, this app is for you. Suitable for both beginners and experienced fasters.

Autophagy

Read full description

Autophagy tracks the five practices most strongly linked to cellular renewal: fasting, exercise, cold immersion, sauna, and Reset Breathing. One daily score, one streak, one clean view of how often you actually do the things that matter. Free to use. No account, no sign-in. WHAT IT TRACKS - Fasting, in hours, with sensible scoring that caps so it never rewards extreme fasting - Exercise, calibrated per type, and optionally imported from Apple Health - Cold immersion, as a live timer - Sauna, as a live timer - Reset Breathing ONE DAILY SCORE Each practice earns up to 20 points a day. The default daily target is 42, and you can change it. The scoring rewards spreading your practice, not maxing out one thing. ON YOUR HOME SCREEN Add the Autophagy widget to your Home Screen or Lock Screen and today's ring, score and streak are one glance away, no need to open the app. APPLE HEALTH Connect Apple Health and your runs, walks and workouts import as exercise automatically, so your score reflects the training you already do. PREMIUM A subscription unlocks the deeper layer: - How your HRV lines up with your cold, sauna and fasting days - Your recovery markers, HRV, resting heart rate and VO2 max, alongside your practice - A plain-language weekly summary - The full practitioner library Premium is a subscription. Annual comes with a 7-day free trial; monthly bills straight away. A NOTE ON HONESTY This is a wellness tracker, not medical advice, and it does not measure autophagy. It tracks practices associated with cellular renewal. Talk to your doctor before starting any new fasting, training, or cold-exposure practice. PRIVACY Your logged sessions and any Apple Health data the app reads stay on your device. The app uses TelemetryDeck for anonymous, aggregate usage analytics, and Google Analytics for Firebase to measure app installs and advertising performance. Neither carries your name or account. Built by a practitioner who actually does the work. Made in England by Alamex Ltd. SUBSCRIPTION DETAILS Autophagy Premium is offered as a monthly or annual auto-renewable subscription. The annual plan includes a 7-day free trial. Payment is charged to your Apple ID at confirmation of purchase.
