Brekk: Intermittent Fasting

Brekk is an intermittent fasting tracker and timer that explains what your body may be doing. It shows the fasting phase you're likely in, from fat burning to ketosis to autophagy, live on screen and in your notifications. Every phase is free. No account, no sign-up. Brekk, as in breakfast: the meal that breaks your fast. It's a calm intermittent fasting app for beginners and seasoned fasters alike. Your Fasting Phases, Explained In Brekk's model of 9 fasting phases, fat burning starts around hour 14, ketosis around 16 and autophagy around 18. A 16:8 fast reaches the first five, up to ketosis. Tap a phase to see what's happening and what you might feel. You may know them as fasting stages or fasting zones; they're rough estimates, not readings from your body. A live timer sits in your notification shade, and an alert marks each new phase up to your goal. Set quiet hours for reminders, and switch off phase, goal, coaching or streak alerts. 19 Intermittent Fasting Schedules Start gently with 12:12, 13:11, the 14:10 Circadian Rhythm or 15:9, then settle into 16:8 and its 8-hour eating window. Or fast a full day a week with 6:1. Pro adds 17:7 to 22:2 (18:6 and 20:4 included), OMAD (one meal a day), 5:2 and extended fasting: single fasts of 24, 30, 36, 48 or 72 hours, with a medical warning. The Auto Scheduler starts and stops fasts at set times on the days you choose. Your personal plan lengthens fasts only when you agree. Food, Weight, Water and Steps Count calories and macros in a food diary, with daily targets. Add food by hand, from recent foods, or from an offline search of 400+ common foods (English names). If weight loss is your goal, the weight tracker charts your weigh-ins over 7, 30 or 90 days next to your target. Plus 5 body measurements, a water tracker (in ml), a step counter with goals and weekly insights, BMI and an electrolyte tracker.

Cancel any time in Google Play. Your Privacy, in Plain Words Your fasting log, weight, measurements and food diary are stored on your phone, not on a Brekk server. The main things that leave it: a meal photo you choose to scan goes to Google's Gemini AI to estimate calories, and a barcode number goes to Open Food Facts. Google Firebase Analytics gets usage events and your quiz answers, like your goal, sex and activity level, but never your weight, health conditions, notes or photos. The free version may show ads from Google AdMob, which uses your device's advertising ID. Analytics and ads also see your approximate location. If Android backup is on, it copies your data to your Google account. The timer and logs work offline; AI and barcode scans need a connection. Before You Start Brekk is for adults. Brekk is not a medical device and does not diagnose, treat, cure, or prevent any medical condition. Talk to a healthcare professional for medical advice and before you start intermittent fasting. It matters most if you're pregnant or breastfeeding, have a history of disordered eating, take medication for diabetes, or live with any medical condition.
