ViATOM SleepU Pulse Oximeter for Android and iOS with app

Wearable oxygen saturation monitor: The patented soft silicone sensor ring completely frees your finger while providing accurate measurements. It stays put on your finger, continuously monitoring your blood oxygen saturation, heart rate, and body movement throughout the night.

Smart Vibration Notifications: SleepU gently vibrates to remind you to change position when it detects your blood oxygen levels drop below a preset threshold, effectively helping you maintain healthy oxygen levels during sleep. The threshold can be adjusted via the app.

Convenient Reports: SleepU can continuously record blood oxygen saturation and heart rate, generating trend reports within the app or via PC software. Reports can be saved in PDF format for printing or sharing with others. The app offers a paid membership, but this does not affect the normal use of basic features.

Smart data management: Built-in memory allows for operation without a phone connection. Data will automatically sync to the app when connected to your phone, and can also be synced to your computer via the included cable. Unlimited data storage at no extra cost.

Rechargeable and energy-efficient: The built-in battery lasts up to 16 hours on a full charge. No buttons – the device automatically turns on when you put it on and turns off 2 minutes after you remove it.
