{"appstoreID":6749188352,"title":"Fast Slow - Fasting Tracker","subtitle":"Intermittent 16:8 Free Timer","developerName":"Zan Cerne","description":"See what happens inside your body as you fast. Fast Slow walks you through 5 fasting zones, from digestion through fat burning to deep ketosis, so you understand what every hour of your fast is doing.\n\n100% free. Every feature. No ads. No paywalls. No trackers. Free forever.\n\nWHAT MAKES FAST SLOW DIFFERENT\n\nMost fasting apps just count down a timer. Fast Slow shows you what's actually happening in your body at each stage:\n\n- Anabolic (0-4h): Digesting and storing nutrients\n- Catabolic (4-8h): Tapping into energy reserves\n- Fat Burning (8-12h): The metabolic switch\n- Ketosis (12-16h): Ketones and cellular cleanup\n- Deep Ketosis (16h+): Deep cellular renewal\n\nTap any zone to learn more about the science behind it.\n\n100% FREE. EVERY FEATURE INCLUDED.\n\nNo premium tier. No trial that expires. No paywall gates. Every feature in Fast Slow is yours from day one:\n\n- All 6 fasting schedules\n- All stats, streaks, and trends\n- All widgets (Home Screen and Lock Screen)\n- All notifications\n- Siri Shortcuts\n- iCloud sync\n- Data export\n\nEverything free. No catches.\n\nFEATURES\n\nFasting Timer\nOne tap to start. One tap to stop. A visual timeline shows where you are, what zone you're in, and what comes next.\n\n6 Fasting Schedules\n12:12 for beginners, 14:10, 16:8 (the most popular), 18:6, 20:4, and OMAD (one meal a day) for experienced fasters.\n\nVisual Timeline\nColor-coded timeline of your fasting and eating windows. Plan meals, training, and recovery at a glance.\n\nSmart Notifications\n7 notification types: goal reached, halfway there, one hour left, eating window alerts, and a custom last meal reminder. Nudges, not nags.\n\nStats & Streaks\nTotal fasts, average duration, personal records, weekly trends, and a monthly fasting calendar. Small wins add up.\n\nWidgets\nHome Screen and Lock Screen widgets with progress rings, timelines, and live timers. Check your fast without opening the app.\n\nSiri Shortcuts\n\"Hey Siri, start my fast.\" Start, stop, and check your fasting status hands-free.\n\nAI-Powered Greetings\nOn supported devices, Apple Intelligence creates personalized messages based on your fasting progress, streak, and time of day.\n\niCloud Sync\nYour fasting data syncs automatically across all your devices.\n\nData You Own\nExport your fasting history as JSON. Delete everything with one tap. Your data, your choice.\n\nDESIGNED FOR REAL LIFE\n\nPick a schedule, adjust as needed, and let Fast Slow handle the timing. New to fasting or already have a routine, it works either way. Structure when you want it, out of the way when you don't.\n\nBuilt by one developer who fasts every day. No corporate agenda. No growth hacking. A well-made tool that respects your time and your data.\n\nRESPONSIBLE APPROACH\n\nIntermittent fasting can support weight management, energy, and focus, but results vary. Fast Slow provides tools and information, not medical advice. If you have health conditions, are pregnant, or have a history of eating disorders, please talk to a healthcare professional before starting.\n\nTerms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/\nPrivacy Policy: https://cernezan.com/fast-slow/privacy/","bundleID":"com.cernezan.fast","appiconURL":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/15/fa/b9/15fab9bc-860e-925a-a550-8ab718ae5b56/Placeholder.mill/1024x1024w.webp","formattedPrice":"Free","appUpdated":"2026-09-19T12:01:46.000Z","appReleased":"2025-08-22T07:00:00.000Z","version":"2.3.0","platforms":["iphone"],"minOS":{"iphone":"Requires iOS 18.0 or later.","mac":"Requires macOS 15.0 or later and a Mac with Apple M1 chip or later.","vision":"Requires visionOS 2.0 or later."},"languages":["EN"],"size":"22.7 MB","category":"Health & Fitness","developerWebsite":"","screenshots":[{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/c1/68/28/c168287f-397b-3639-0021-e38c15027ad2/sc1.png/1284x2778w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/24/3e/95/243e95fd-2aec-8256-f7ae-333a24ac4516/sc2.png/1284x2778w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/14/63/22/1463228e-7d10-0f02-fa72-db70481cc2e9/sc3.png/1284x2778w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource221/v4/82/6a/78/826a78c0-438c-11c1-76a8-96ec741ccdc1/sc4.png/1284x2778w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/03/d0/14/03d01467-ca8e-4713-af06-8bd90cfdc1be/sc5.png/1284x2778w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/4e/f9/95/4ef9953e-7774-ef48-9747-9316151f1b5a/sc6.png/1284x2778w.webp"},{"platform":"iphone","url":"https://is1-ssl.mzstatic.com/image/thumb/PurpleSource211/v4/42/b8/97/42b89792-0d33-2ea2-1189-51570666bdb6/sc7.png/1284x2778w.webp"}]}
