Blood oxygen and heart-rate measurements occur automatically; enable continuous or spot checks in the Withings app. Temperature tracking runs day and night through the TempTech24/7 Module and is processed alongside heart rate and motion data to establish baseline variations. Sync the watch with the Withings app via Bluetooth to view detailed trends and sleep assessments.

Recommendations

For best measurement accuracy, fasten the watch correctly on the wrist, avoid excessive movement during spot measurements (ECG/SpO2), and keep the watch paired with the Withings app to maintain updated baselines and receive notifications about metric shifts.
