About

life.fan

Features
Read full description

life.fan builds a longevity plan around your actual life — then adapts when your life changes. Tell it your goals, your schedule, and your exceptions (Wednesday night out? It's in the plan). It builds a research-backed routine for fasting, training, recovery, and supplements — every recommendation cited to published studies, with links to the sources in the in-app Research library. THE FAST CLOCK RUNS ON REAL MEALS Log food or drink with one tap and the fasting ring tracks what's actually happening in your body — glycogen burn, fat burn, cellular cleanup — not a schedule you set once and forgot. Notifications nudge you based on when you really ate. YOUR SCALE AND WATCH, ONE PLAN Connects read-only to Apple Health: weight, body fat, HRV, resting heart rate, sleep, steps, and workouts. Daily target rings show where you stand. Workouts logged by your watch check themselves off automatically. RESEARCH, NOT VIBES Every rule in your plan carries a citation. If something in your existing routine conflicts with the evidence — cold plunge right after lifting, training at your weakest hour — life.fan surfaces it as a suggested edit, with the study behind it. KNOW YOUR NUMBERS Metabolic age, longevity score, maintenance calories, and lean mass — computed from your own measurements, with the method explained in plain language. SUPPLEMENTS, ASSESSED Type a name or scan a label and get a goal-personalized verdict — beneficial, situational, or caution — backed by sources. Already taking something? It's assessed against your goals, including interactions worth knowing about. MAKE IT YOURS Neon lime or neon pink signal color by default — or pick any custom color. Every rule is editable, any time. life.fan reads from Apple Health and never writes to it. Your health data never leaves your device. MEDICAL DISCLAIMER life.fan provides research-based wellness information and is not a medical device. It does not provide medical advice, diagnosis, or treatment. Always seek the advice of your physician or another qualified health provider in addition to using this app, before beginning any fasting, exercise, or supplement regimen, and before making any medical decisions.
