OutPerform Health Tracker vs Endyr.AI

Know your body. Then outperform. OutPerform turns the health data you already have into clear daily guidance — 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-α1), resting heart rate, breathing rate and sleep — 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 — 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 VO₂ 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 — 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 — RMSSD/DFA-α1 HRV, Banister TRIMP, acute:chronic workload ratio, the Three-Process Model of alertness, Gellish max-HR, Åstrand VO₂ and more — and shows you the formula behind every number.

Everything you track sees part of the picture. Endyr reads all of it — training, recovery, sleep and fuel — and makes one call for the day. YOUR MORNING, AS WEATHER Your readiness arrives as a sky. The colour of the screen tells you how the night went before you read a single number, and one line says what it means for today. Underneath, a short brief explains what changed and why — measured against your own baseline, not a population average. EVERY SESSION, CAPTURED Start a session, tick blocks off as you go, log results block by block, and rate how hard it felt once you're done. Your coach's plan is there if you have one. Train yourself? Endyr writes your training — join in the app, answer a few questions, and your first session is ready before you've laced up. YOUR BODY, EXPLAINED Sleep and its stages, heart-rate variability, resting heart rate, respiratory rate, body composition — each shown against your own baseline, so the explanation matches the number you woke up to. FUEL Log a meal by photo, text or barcode. Save the ones you eat often, search foods, set one target for every day — or split training and rest days — and watch the week trend. ASK A coach you can ask anything, answering from your own data rather than general advice. FOR COACHES A squad roster that says who needs you first, each athlete's day in detail, a training review, competitions, and weekly programming you can write from your phone. CONNECTS TO WHAT YOU ALREADY USE Endyr reads from the major wearables, watches, rings, straps, smart scales, strength apps and nutrition trackers — and from anything that writes to Apple Health or Health Connect. Connect once and it keeps itself current. NO WEARABLE? IT STILL WORKS. Answer five questions in the morning and Endyr reads your day from those. The part that matters most — how much you can absorb — doesn't need a device. Endyr is a coaching and informational tool, not medical advice. Apple Health access is read-only and never used for advertising. Terms of Use: https://endyr.ai/terms.html
