Fastan: Fasting Tracker

Fastan is the intermittent fasting tracker with no plans and no quizzes. It is already tracking when you open it. There is no start button. Your fast is always running. The only thing you ever do is tap "I just ate". That one tap logs your meal and resets the clock. Everything else happens on its own. ONE TAP, THAT IS ALL • Tap "I just ate" and your fasting clock restarts from zero • Tapped by mistake? Undo within 10 seconds • Forgot to tap? Edit your last meal time whenever you like. Every fast stays editable SEE WHAT YOUR BODY IS DOING Fastan is a metabolic phase tracker. As the hours pass, it shows which fasting phase you are in and what your body is doing right now: • Fed (0 to 4 hours): digestion, insulin elevated • Early Fasting (4 to 12 hours): glycogen becomes your main fuel • Fat Burning (12 to 16 hours): your body switches to fat for energy • Ketosis (16 to 24 hours): ketone production ramps up • Autophagy (24 to 48 hours): cellular cleanup • Deep Fast (48 hours and beyond): deep ketosis A breathing progress ring fills toward your next phase, never toward a goal, and a 72 hour phase strip shows exactly where you are. KNOW THE MOMENT EACH PHASE BEGINS • A notification at every phase transition, like "Fat burning has begun" • Quiet hours hold a notification until morning • A fasting tracker that stays out of your way until a phase begins • Intermittent fasting phases explained in plain language • No streak guilt, no check-ins, no nagging. Ever A HISTORY THAT STAYS CLEAN • Every gap of 4 hours or more between meals counts as a fast, so snacks never clutter your history • 7 and 30 day charts of your longest fast each day, colored by the phase you reached • Stats that matter: longest fast, 7 day average, days reaching 16 hours, total hours in ketosis FASTAN PRO • Cloud backup and sync across your devices • A weekly fasting insights digest every Monday • Phase notifications with quiet hours WHAT FASTAN DOES NOT HAVE No fasting plans. No goals. No weight tracking. No quizzes. No coaching. No social feed. If you do 16:8, OMAD or any other intermittent fasting rhythm and you are tired of apps that want to manage you, Fastan simply keeps time and tells you what is happening. No account needed. Fastan works the moment you open it, and you can save your history with Google or email whenever you want. Fastan is a tracker, not medical advice. Talk to a doctor before fasting if you are pregnant, have diabetes, have a history of eating disorders or take medication. Subscriptions renew automatically until cancelled.
