Meet your private fasting coach. MindFast times your fasts, shows each fasting stage as it happens, and gives you one clear tip at a time, drawn from your own fasts. No account, no ads, no tracking. A COACH THAT KNOWS YOUR FASTS • Ask anything, like "Why do my fasts end early?", and get answers that draw on your own fasting history • The coach card on the timer checks in through every fast, based on how your past fasts went • Tap "I'm struggling" for help getting through a hard hour • When the fast ends, get ideas for what to eat first ONE CLEAR TIP, EVERY WEEK • Weekly Review: what you planned next to what you did, a score, and the one change that matters most. Apply it in one tap. • Monthly Report: a score, a summary and next steps for the month ahead • Goal Coach: a game plan for your weight, energy, sleep or health goal. It checks your pace each week and suggests one change. FAST YOUR WAY • Daily fasts from 12 to 23 hours, including 16:8, 18:6, 20:4 and OMAD • Plan each day of the week, set up 5:2, or try alternate-day fasting • Start an unplanned fast whenever you like • Reminders when it's time to fast and when you reach your goal SEE YOUR PROGRESS • Follow each fasting stage live, from early fasting to ketosis • Streaks, stats, charts and a calendar of every fast • Weight, energy, sleep and health goals • A journal for how each fast feels • A Home Screen widget with your current fast STAY MOTIVATED • Weekly challenges that earn XP • Eight titles to earn, from Fasting Novice to Enlightened One • Badges and monthly medals PRIVATE BY DESIGN • No sign-up, no email, no ads and no third-party tracking • Your fasting history is stored on your device, not in a MindFast account • The AI Coach uses Apple Intelligence. On iOS 27, some answers come from Apple's Private Cloud Compute, which Apple built so your requests are never stored or made accessible to Apple. APPLE HEALTH MindFast can read your height, weight, age and sex from the Apple Health app to set up your profile, and save the weights you log back to it. You choose what to share. FREE AND PREMIUM Your first fast unlocks every Premium feature, with no sign-up. After that, the timer, fasting stages, the coach card, 16-hour daily fasts and challenges stay free. MindFast Premium adds the AI Coach, Weekly Review, Monthly Report, goals with the Goal Coach, custom and weekly schedules, advanced insights, your full history and the widget. Choose a monthly or annual subscription, or a one-time lifetime purchase. Eligible new subscribers can start with a free trial. Payment is charged to your Apple Account. Subscriptions renew automatically unless cancelled at least 24 hours before the end of the current period. Manage or cancel them in your App Store account settings. The AI Coach works best on iOS 26 or later with Apple Intelligence turned on. MindFast does not give medical advice. Talk to your doctor before you start fasting, especially if you are pregnant or breastfeeding, have diabetes or another medical condition, take medication, or have a history of eating disorders.
