Frequently asked

Sizing, accuracy, battery, and app requirements. If your question isn't here, email us at support@harmonea.io.

No, the Band is free size. Its adjustable mesh strap fits every wrist; set the magnetic clasp where it sits snug, about a finger-width above the wrist bone, for accurate HRV and SpO₂ readings.

The 500 Hz Goodix ECG and dual-PD optical array are validated against clinical reference equipment, with HRV agreement typically within a few milliseconds at rest. It is a wellness device, not a diagnostic tool, and is not a substitute for medical care, but the data is good enough that physicians on our team use it daily.

Yes. The Band is rated IP68, so showering and pool swimming are fine. Rinse with fresh water after salt or chlorine, and dry the charging contacts before placing it on the cable.

The G Band app runs on iOS 13+ and Android 8+, over Bluetooth 5.3. It syncs Board sessions, surfaces long-term trend charts and health breakdowns, and exports raw data to CSV, Apple Health, and Google Fit.
