Fastwell is an honest intermittent fasting timer that shows you what's actually happening inside your body — right on your Lock Screen and Dynamic Island. Start a fast, and Fastwell tracks your journey through the real metabolic stages: glycogen depletion, fat burning, ketosis, and autophagy. No guessing, no gimmicks — just a clear, science-based timeline of where you are and what comes next. The core is free forever. No fake trials, no surprise charges, no locking your own timer behind a paywall. WHY FASTWELL • Fasting stages on Live Activity & Dynamic Island — glance at your phone and instantly see if you've hit fat burning or ketosis, without opening the app. • A timer you can actually trust — start, pause, edit your start time, and finish honestly. • Popular windows built in — 16:8, 18:6, 20:4, OMAD, or set your own custom window (12–36h). • Streaks & progress — build momentum with streaks, best-streak tracking, weekly stats, and trend charts. • Weight & BMI tracking — log your weight, see trends, and sync with Apple Health. • Home Screen & Lock Screen widgets — your current stage and countdown, always visible. • Smart reminders — get notified when your fast completes or your eating window is about to close, with quiet hours respected. • Learn the science — clear, no-hype articles on fasting basics, metabolic stages, weight, and longevity. HONEST BY DESIGN Your timer, windows (16:8/18:6), history, streaks, and Live Activity are free — forever. Fastwell Premium unlocks deeper insights, locked custom windows, and expert stage breakdowns, but the essentials never disappear. Fastwell Premium (optional) • Weekly and Yearly plans available. • The Yearly plan includes a 7-day free trial. • Payment is charged to your Apple ID account at confirmation of purchase. • Subscriptions renew automatically unless auto-renew is turned off at least 24 hours before the end of the current period. • Manage or cancel anytime in your App Store account settings. • Any unused portion of a free trial is forfeited when you purchase a subscription. Fastwell is a wellness and educational tool. It is not medical advice and is not intended to diagnose, treat, cure, or prevent any disease. Consult your doctor before starting any fasting program, especially if you are pregnant, nursing, taking medication, or have a medical condition.
