Every game leaves more than a score. It leaves data in your body. PlayBurn is an energy and body-data tracker made for gamers with watch. Choose a game type before you play, record heart rate and active energy during the session, then get a clear post-game body report on your phone. SEE WHAT A GAME BURNS • View active energy calibrated for seated gaming • See energy used beyond your resting burn • Convert active calories into an easy-to-understand jogging-time equivalent • Review total play time and active energy across 7- and 30-day trends REPLAY YOUR BODY'S RESPONSE • Explore average, peak, and minimum heart rate with a full session chart • Find peak heart rate, high-arousal segments, calm periods, and recovery windows • Follow estimated excitement, focus, stress, fluctuation, recovery, and gaming-load trends • Review a body-state timeline for each session KEEP A BETTER RHYTHM • Get one consolidated post-game rest suggestion when sustained load, slower recovery, or a long session is detected • Stay interruption-free while you play; suggestions only appear after a session • Compare your own patterns over 7 and 30 days BUILT FOR WATCH AND PHONE Watch handles session controls and live essentials. Your phone handles reports, history, and trends. If your phone is out of range, the watch keeps the session and transfers it after reconnecting. PRIVATE BY DESIGN Analysis happens on device. PlayBurn requires no account and does not upload health data, gameplay, recordings, or chats. Gaming sessions are not written to Health or the Fitness app. ABOUT ENERGY AND BODY METRICS Active energy comes from watch and is calibrated for seated gaming. It is an estimate of energy beyond resting burn, not a promise of weight loss. Excitement, focus, stress, recovery, and related scores are estimates of physiological trends, not medical measurements, diagnoses, or readings of actual emotion. If you feel unwell, stop playing and seek appropriate professional help. Compatibility: Full session tracking requires Watch and permission to read relevant Health data.
