Know your body. Then outperform. OutPerform turns the health data you already have into clear daily guidance β€” so you know when to push, when to rest, and when your mind is sharpest. Everything is computed privately on your iPhone using transparent, published sports-science methods. No accounts. No servers. No subscription. Connect Apple Health or Google Health, and OutPerform reads your heart rate, HRV, sleep, breathing, blood oxygen, temperature and workouts to give you: RECOVERY A morning recovery score from your overnight HRV (RMSSD / DFA-Ξ±1), resting heart rate, breathing rate and sleep β€” each measured against your own personal baseline. STRAIN & TRAINING LOAD Cardiovascular load on a 0–21 scale, plus acute-to-chronic workload ratio and training monotony, so you build fitness without overreaching. SLEEP Sleep stages, efficiency and a performance score, a dynamic nightly sleep-need target that rises with the day's strain, and a smart bedtime recommendation. COGNITIVE FOCUS Predict how "locked in" you'll be hour by hour and find your peak deep-work windows β€” then calibrate it to yourself with a one-minute reaction test. READINESS One daily number that folds recovery, last night's sleep and your training-load balance into a clear go / steady / rest call. HEALTH MONITORING Track blood oxygen, respiratory rate, skin temperature and VOβ‚‚ max against your baseline, with an overnight breathing-disruption (ODI) screening signal. PLUS - Scrubbable 7/30/90-day trends for every metric - A tap-through explanation of how each score is calculated - Home-screen widgets - Export all your data, or wipe it, any time PRIVATE BY DESIGN Your health data never leaves your phone. OutPerform has no backend and no account β€” every score is computed on-device, and nothing is ever sold or shared. Connections to Apple Health and Google Health are read-only. GROUNDED IN SCIENCE No black boxes. OutPerform uses peer-reviewed methods β€” RMSSD/DFA-Ξ±1 HRV, Banister TRIMP, acute:chronic workload ratio, the Three-Process Model of alertness, Gellish max-HR, Γ…strand VOβ‚‚ and more β€” and shows you the formula behind every number. Free to use. β€” OutPerform is not a medical device and does not diagnose, treat or prevent any condition.
