2. Body Temperature Monitoring: Real-time skin temperature tracking for health trends.
Heart Rate Monitoring:Continuous optical HR sensor detects beats per minute (BPM).
Blood Pressure Monitoring: Estimates blood pressure via PPG sensors (not medical-grade).
Blood Oxygen Monitoring/SpO2: Measures blood oxygen saturation (%) during sleep or workouts.
Combines GPS + AGPS (Assisted GPS) + BDS (BeiDou) + WiFi + LBS (Cell Tower) for accurate location tracking indoors/outdoors.
Automatically enters low-power mode when no motion is detected.
Syncs with smartphones to display calls, SMS, and app alerts (e.g., WhatsApp, WeChat).
Audible alerts for alarms, health thresholds, or navigation.
Long-press a button to send distress signals with location to pre-set contacts.
Alerts when battery drops below a threshold (e.g., 10%).
Syncs and displays contacts from paired smartphones.
Records and maps exercise routes (walking/running/cycling) via GPS.
Virtual boundaries trigger alerts when the watch enters/exits a defined area.
