Hiyd Health is the companion app for the Hiyd Tracker — a discreet sensor that attaches under the classic watch you already wear (or onto the Hiyd SoftBand) and quietly turns it into a modern health tracker. No screen on your wrist, no charging cradle on your nightstand competing with the watch you love — just your watch, with sensing underneath. Human sensing, quietly present. LIVE HEART RATE See your heart rate in real time, measured on-device by the Tracker's optical sensor and streamed to your iPhone over Bluetooth. SLEEP, SCORED Wake up to a nightly Sleep Score with a full breakdown of your sleep stages — light, deep, and REM — plus duration and consistency trends over time. YOUR DAY IN SCORES Follow steps, heart rate variability (HRV), a morning Readiness score, and a daily Move score that together give you a clear picture of activity and recovery. WORKOUTS WITH HEART RATE ZONES Track 12 workout types with live heart rate zones, so you always know how hard you're working — from easy walks to interval sessions. MEALS AND MACROS Log meals in seconds and keep an eye on calories, protein, carbs, and fat alongside your activity. APPLE HEALTH SYNC Connect Apple Health to keep your heart rate, sleep, steps, and workouts in one place. You choose exactly what is shared, and you can change it at any time. ALWAYS UP TO DATE Firmware updates for your Hiyd Tracker install right from the app — no cables, no computer. A HIYD TRACKER IS REQUIRED Hiyd Health requires a Hiyd Tracker to measure heart rate, sleep, and activity. Health tracking features only work with the wearable, worn under a classic watch or on the Hiyd SoftBand. Learn more at hiyd.ai.

They are intended for general fitness and wellness purposes only and are not designed to diagnose, treat, cure, or prevent any disease or medical condition.
