StayFasted is the fasting app that actually keeps you going. Most fasts don't end because of the plan. They end in one hard half hour. StayFasted is built around that half hour: a timer you can trust, a guide to what to expect, and a check-in that answers back. A TIMER FOR EVERY FAST 16:8 · 18:6 · 20:4 · One Meal a Day · 36h · 48h · 72h. One button starts it. Forgot to start? Move the start time in seconds. Your fast also shows on your Lock Screen, in the Dynamic Island, in widgets and on Apple Watch. KNOW WHAT TO EXPECT, HOUR BY HOUR For each part of a fast: what is generally understood, what people often feel, and what tends to help. Timing differs from person to person. General information, not medical advice. CHECK IN WHEN IT GETS HARD Mood, hunger and energy in a few taps. With Pro, an AI replies to what you wrote, how you feel and why you started. It runs on your iPhone, and it never pushes you to carry on. BREATHE Short breathing sessions for the moment a craving arrives, and a guided deep rest for when you need to lie down for ten minutes. On your phone and on your wrist. FLUIDS AND ELECTROLYTES Log water, coffee and tea in one tap. See whether you are keeping an even pace through the day. Electrolyte reminders for longer fasts. END IT WELL Stop whenever you choose. A refeed guide walks you back to food gently, from liquids to normal meals. SEE YOUR PATTERNS Insights in plain words from your own data, always honest about how much data they are based on. Progress photos on a timeline. A monthly report you can share with your doctor or coach. APPLE WATCH See your fast, start or end it, log water, check in and breathe. APPLE HEALTH Optional. Reads weight, steps, sleep, resting heart rate and active energy. Saves weight, water and mindful minutes. You choose what to share. YOUR FASTING DATA STAYS ON YOUR PHONE No account and no sign-up. Your fasts, check-ins, photos and notes are stored on your iPhone. Three optional features use the internet, only if you turn them on: weather, scanning a drink's barcode, and Apple Music playlists. FREE - Timer for every fasting length - The hour-by-hour guide - Check-ins, fluid tracking and the refeed guide - Two breathing sessions - Apple Watch, widgets and Live Activities - Your last 10 fasts and 7 days of charts PRO - AI replies on every check-in - All breathing sessions and deep rest - Full analytics and a monthly report with PDF - Unlimited history, journal, measurements and supplements - Rhythm planner, drink scanner, photo comparison - Health Labs scanner for InBody, DEXA and blood panels - CSV export Pro: $5.99 a month or $39.99 a year. Lifetime: $49.99, one payment. StayFasted gives general information about fasting and is not medical advice. Talk to your doctor before you start fasting, especially if you are pregnant, under 18, have diabetes or an eating disorder, or take medication.
