OutPerform Health Tracker
Health & Fitness
Free · Designed for iPad. Not verified for macOS.
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.

Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
OutPerform can now pair directly with your Fitbit Air (or any Bluetooth heart-rate band) and work out sleep, HRV, recovery and strain right on your iPhone, with no cloud. A new “All sources” mode combines Apple Health, Google Health and the band, taking each piece of data from whichever source has it. There are also customizable heart-rate zones with phone alerts, and a new Exercise tab for tracking workouts with live heart rate, GPS pace/distance/route, steps and elevation. New: an optional AI coach on the Today tab. Connect Claude (Anthropic) or ChatGPT (OpenAI) with your own API key, and get a daily brief plus a chat about your recovery, sleep and training. Plus faster syncs and a fix for the missing Apple Health permission prompt. Everything is processed privately on your iPhone. The AI coach is the only feature that sends anything out, and only once you set it up: it talks directly to the provider you pick, and shares your scores only if you opt in.
