About the bracelet
Optics (PPG) measure heart rate from reflected light and don't register the heart's electrical activity. WitU's two electrodes record a true ECG — with arrhythmia detection. Measurement accuracy is 10% higher than PPG.
No. The core features — ECG, HRV, heart rate, sleep — work without a subscription forever. A subscription is only needed for advanced AI services (supplement recommendations, lab test analysis). Premium costs $9.99/mo (the annual plan saves you 2 months). The device's core features work without a subscription.
Titanium Grade 5 (from $399), silver 925 (from $699), gold 750 (from $2,499), and platinum 950 (from $7,999). The sensor module is identical in all of them — only the material and the price differ.
Up to 7 days with active use. A full charge takes about 90 minutes on the magnetic pad.
