5 devices on a single platform. ECG, HRV, SpO₂, temperature — all data synced in real time.
Free for iOS and Android. Works without the bracelet too — with Apple Watch, Garmin, and Polar.
The only ecosystem that turns device data and lab test results into personalized recommendations.
High-precision optical sensors read your pulse wave (PPG), HRV, SpO₂, and temperature straight from the wrist. Sterling silver 925 and natural agate keep the read clean and the signal clear — a piece of jewelry and a full health tracker.
01Upload a form from your lab — the system recognizes biomarkers in 30 seconds and factors your real biochemistry into its recommendations. No competitor can do this.
02Supplements, nutrition, training, and recovery — tailored to your sensor and lab data. Not generic advice from the internet, but concrete steps for today.
03Every sensor sees its own piece. Together they see the full picture of your health — in sync, in real time.

AI recommendations for supplements, nutrition, and training — based on your real data. Works without the bracelet too: Apple Watch, Garmin, Polar.
WITU·0505 / 05 2026 Q3Reference-grade heart-rate accuracy
A chest strap with ECG-grade heart-rate accuracy for training. Real-time R-R and HRV under load — where wrist optics fall short.
Jewelry-grade optical sensors on the wrist, real ECG across the ecosystem, and a live human concierge — no subscription.
The bracelet is optical — but WitU still gives you a true cardiogram through the WitU Patch (continuous ECG, up to 14 days) and the Chest Strap (dry electrodes). Neither Oura nor Whoop offers ECG at all.
Every second, not once every 15 minutes. A Recovery Score built on real heart-rate-variability data across a full 24 hours.
