Wearable Blood Oxygen Saturation Monitor Uses a patented soft silicone ring sensor that completely releases the finger while ensuring accurate measurements. It will not slip off the finger and continuously monitors blood oxygen saturation, heart rate, and physical activity during sleep throughout the night.

Smart Vibration ReminderWhen SleepU detects that your blood oxygen level is below the preset threshold, it will gently vibrate to remind you to adjust your posture, helping you fall asleep in a healthy blood oxygen state. You can adjust the threshold settings via the app.

Convenient ReportsSleepU continuously records your blood oxygen saturation and heart rate, and generates trend reports in the app or computer software. You can save the reports in PDF format for printing or sharing with others.

Intelligent Data Management Built-in storage space allows it to operate independently without connecting to a mobile phone. When connected to a mobile phone, data will be automatically synchronised to your app. You can also synchronise data to your computer using the included data cable. Provides unlimited storage space at no additional cost.

Rechargeable and energy-efficientThe rechargeable battery can be used continuously for up to 16 hours after being fully charged. The device does not require button operation; it starts automatically when worn and turns off automatically two minutes after the finger is removed from the probe.
