Rythm: Recovery & Strain

Rythm turns the health data your Apple Watch already collects into a clear, daily read on how ready your body is — no extra hardware, no chest strap, no new sensors. Every morning, Rythm scores your Recovery from overnight heart rate variability, resting heart rate, sleep, and blood oxygen — all measured against YOUR personal baseline, not a generic population average. Then it tracks the strain you put on your body through the day and the stress your system is carrying, so you know when to push and when to rest. WHAT YOU GET • Recovery score — one number for how recovered you are today, with a breakdown of what's driving it • Sleep tracking — duration, efficiency, and deep/REM stages, scored for quality • Strain & stress — training load from your heart-rate zones, plus non-exercise stress • Trends — recovery, HRV, sleep, and strain over weeks and months, with your personal normal range • Cardio Fitness Age — how your heart-and-lung fitness compares to your actual age • Private AI insights — plain-language guidance generated entirely on your device BUILT AROUND YOUR BASELINE Rythm learns what's normal for you and highlights meaningful changes — a low-HRV day, a short night, a rising resting heart rate — instead of comparing you to strangers. Calibration is instant: Rythm reads your Apple Health history the first time you open it. PRIVATE BY DESIGN There's no account and no sign-in. Your health data never leaves your iPhone — scores and AI insights are computed entirely on device, and nothing is uploaded or shared. WHO IT'S FOR Runners, cyclists, lifters, and anyone who wants to train smarter, sleep better, and avoid burnout using the Apple Watch they already own. Rythm is a personal wellness tool, not a medical device. It does not diagnose, treat, or prevent any condition. Always consult a qualified professional for medical advice.
