How accurate and continuous is the heart-rate and SpO2 monitoring?

The device performs continuous optical heart-rate monitoring and regular SpO2 checks throughout the day so you can review trends and spot unusual changes. Measurements are available instantly on the watch and stored in the companion app for historical charts and comparisons. While the sensor gives helpful daily insights, it is intended for lifestyle tracking rather than medical diagnostics.

• 24/7 optical heart-rate sensing with instant on-screen readouts
• Automatic and manual blood-oxygen (SpO2) checks
• Data syncs to app for trend charts and exporting basic history

Can it help me understand and improve my sleep?

The tracker auto-detects light and deep sleep phases plus wake times, compiling a sleep score and basic suggestions to improve nightly rest. You can review nightly breakdowns in the app and compare sleep patterns over weeks to spot consistent issues. It also supports gentle alarms and bedtime reminders to build healthier habits.
