OutPerform Health Tracker vs Apex Trace

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. Free to use. — OutPerform is not a medical device and does not diagnose, treat or prevent any condition.

Your Fitbit data, beautifully visualized — and entirely on your phone. Apex Trace turns the health data you already track into a dark, animated dashboard worth opening every morning. It reads your data through the Google Health API and renders it as ring gauges, real hypnograms, activity heatmaps, and long-term trends. No flat charts. No monthly bill. PRIVATE BY DESIGN — NOT BY PROMISE Most health apps ask you to trust their servers. Apex Trace doesn't have any. • No backend. Your health data never leaves your device — there's nowhere for it to go. • No account, no tracking, no ads. Nothing to sign up for, nothing following you around. • Limited Use. Apex Trace's use of Google data follows the Google API Services User Data Policy, including the Limited Use requirements: your data powers only the features you see — never advertising, never sold, never used to train AI. • Optional crash reports are off by default, and never contain health data. Disconnect anytime and Apex Trace revokes its access and wipes every cached byte from your device. WHAT YOU GET • Today — your whole day at a glance, with animated ring gauges and an at-a-glance readiness estimate computed from your own data. • Sleep — a real hypnogram showing stages, timing, and how last night compares to your baseline. Finally readable. • Fitness — activity heatmaps and heart-rate zones that show effort and consistency over time, not just a single number. • Trends — long-term patterns across your metrics, so you can spot what's actually changing week over week and month over month. PAY ONCE. $6.99. No subscription. No in-app purchases. No ads. Buy it, own it. Get premium-style daily estimates without the premium-style monthly bill. TRY IT BEFORE YOU CONNECT Apex Trace ships with a full sample mode, so you can explore the entire dashboard with example data before you buy or connect anything. WHAT YOU'LL NEED (companion app) Apex Trace reads your data through the Google Health API, so it needs: • The Google Health app installed, and • A connected account syncing into it (a Fitbit account is the most common source). Apex Trace does not connect to Fitbit directly, and there's no account to create with us. A NOTE ON THE NUMBERS Apex Trace's readiness, sleep, and cardio-load figures are its own estimates, computed on your device to help you spot patterns. They are not medical advice, and not any other product's official scores. Fitbit and Google Health are trademarks of Google LLC.
