Health & Lifestyle Functions

Since daily wellness monitoring is the core design goal, the VO190 combines ECG, PPG vital tracking and sleep analysis features.

Vital Sign Monitoring

The watch captures single-lead ECG heart rhythm snapshots. Moreover, it delivers 24-hour continuous PPG heart rate tracking with over 97% lab-tested accuracy. It also supports intermittent SpO₂ blood oxygen measurement and sends vibration alerts when SpO₂ hits preset thresholds; this alert automatically disables during sleep. Readings may show deviations due to strap tightness, blood perfusion, tattoos, arm hair, body movement artifacts and ambient temperature.

Multi-Phase Sleep Analysis

The accelerometer automatically records multi-stage sleep data, including light sleep, deep sleep and REM sleep cycles. The watch stores data temporarily on the device locally, then syncs sleep archives to the companion app once Bluetooth reconnects.

Sport & Activity Tracking

This model includes more than 15 pre-set sport modes for light to moderate exercise. It logs step count, calorie consumption and workout duration. In addition, it saves activity records offline locally and auto-syncs historical sport data to the paired mobile app.

Smart Notifications & Custom Watch Faces

The watch vibrates to alert users of incoming Bluetooth calls and app messages. Users can select multiple custom watch face themes directly on the device.

Auxiliary Daily Tools

Besides wellness and sport tracking, the VO190 handles local timekeeping. All ECG waveforms, vital metric history, sleep reports and sport trend charts display inside the companion wellness mobile app. The app also provides encrypted cloud backup for long-term biometric records. This watch does not have standalone GPS, body temperature tracking or female cycle logging.
