ChronoFast AI vs CaloNet

Most fasting apps are a countdown. ChronoFast AI is a coach that answers the question you actually have at hour 11: does this break my fast? DID I BREAK MY FAST? Type what you had, or snap a photo of it. The AI weighs it against the exact stage your fast is in and gives a straight verdict — Intact, Impacted or Broken — with what it does to insulin, fat burning and autophagy. If it is genuinely broken, one tap ends or restarts the timer. ON YOUR LOCK SCREEN ALL DAY Start a fast and the Live Activity stays with you for the whole thing, drawing the same dial the app does: a ring sweeping through every stage colour, each one checked off as you pass it, with your stage, time elapsed, when the next stage lands and the clock time you finish. Add 250 ml logs your water; End fast opens the app's own confirmation, with undo. The Dynamic Island gives the dial and percentage at a glance, the full status on a press and hold — and one switch in Settings turns it all off. A TIMER THAT SHOWS ITS WORKING • A live dial with your percentage of goal at the centre • A 24-hour band that shows when you eat, and whether your window is drifting later • A named stage track — Fed, Fat Burning, Ketosis, Deep Autophagy — hour-stamped for your plan • Home Screen widgets in two sizes, plus a Lock Screen circular accessory • 12:12 through 20:4, 23:1 OMAD, extended 24h to 72h fasts, or your own custom window • Streak repair: one free rescue a month for a single missed day SCIENCE YOU CAN CHECK Every metabolic stage carries its source — the NEJM fasting review, the Nobel-winning autophagy research — named, dated, and honest where the evidence is still early. The Metabolic Wave glucose curve is clearly labelled as an educational simulation modelled from your clock, never measured from your body. No bro-science, no numbers we cannot know. YOUR ACTIVITY AND SLEEP COUNT With Apple Health connected, ChronoFast reads sleep, resting heart rate, HRV, steps, workouts and active energy, each compared against your own 7-day average. A fasted walk shows as real metabolic progress. A rough night, and the app eases off instead of pushing you to extend. It writes back too — water, weight, nutrition and completed fasts — with a switch for each. FOOD, WATER AND WEIGHT IN ONE PLACE • AI meal scan from a photo, plus barcode scanning for packaged food • Calories and macros on one compact card, with rings that fill as you log • Hydration goal set from your body weight, with reminders that never collide with a stage alert • Weight trend with a projected goal date that shows its confidence band YOU ARE NOT ALONE AT HOUR 16 Fast with buddies added by QR or friend code, see who is fasting right now, send high-fives, join weekly and monthly challenges, log how the fast actually feels on a 1-5 mood scale, and climb a global leaderboard. A shareable weekly recap rolls up your last 7 days. PROGRESS THAT MAKES SENSE A 28-day consistency grid read three ways — fasting, weight and water — a day-by-day log for every metric, and plain-language observations about your last four weeks, each with its evidence. BUILT TO BE TRUSTED 18 languages including full right-to-left Arabic. An adults-only age gate before any health question. A legal centre in plain English, explicit AI-processing consent, and crash reports that never carry your name. Moving phones? Export everything at once. FREE AND PRO The timer, stages, logging, community and daily AI coaching are free. Pro unlocks unlimited AI insights and food scans, all five coach personas, predictive goal dating, the glucose chart and a 100% ad-free app. IMPORTANT ChronoFast AI is for education and general wellness, not a medical device: it does not diagnose, treat or prevent any condition, and AI output can be wrong. Talk to a doctor before fasting if you are pregnant or breastfeeding, under 18, diabetic, on medication, or have a history of disordered eating.

To lose weight, one number determines everything: calories eaten minus calories burned. When it's negative, you're losing. When it's positive, you're not. CaloNet shows you that number — clearly, every day. Open the app and see instantly whether you're in a deficit or surplus. The entire UI turns green when you're on track, red when you're not. No math. No guessing. Just the answer. SNAP A PHOTO. GET EVERY MACRO. Photograph any meal and our AI identifies every ingredient, estimates portions, and returns a full calorie and macro breakdown in seconds. Made a mistake? Describe the correction and we'll re-analyze. YOUR BURN, TRACKED AUTOMATICALLY. Syncs with Apple Watch, Oura, Whoop, Garmin, Fitbit, and any wearable via Apple Health and sees all your active calories and workouts. No wearable? We estimate your burn from your metabolic profile and update automatically when real data arrives. BUILT AROUND YOUR GOAL. Tell us your goal weight, activity level, and target pace. We calculate your personal deficit target, projected weekly loss, and goal date. SEE IT ALL DAY, WITHOUT OPENING THE APP.
