Oximeter monitors your oxygen and heart rate levels. You need a compatible device - oximeter, or there are few wearables that allow us collecting SpO2 data too. See Breath rate detection and oxygenation measure docs for details.
The compatible oximeters are Berrymed oximeters with custom firmware. We did try a lot of oximeters that are on the market and these had the most reliable data.
Currently, only some Wear OS powered wearables can be used for SpO2 monitoring. Garmins and Galaxy watches are hopefully coming soon.
|We have tested TicWatch 3. If you have Wear OS watch that can monitor SpO2, but this data are not collect by Sleep, please send us your application log (Left ☰ menu → Report a bug) and we will use the information from the log for adding support for this watch too.|
Settings → Wearables → Pulse oximeter
|Pulse Oximeter (Bluetooth)||
Enable the feature for compatible oximeters.
|Pulse Oximeter (Wear OS…)||
Enable the feature for compatible wearables.
|Low breath rate alarm||
If enabled, an alarm will wake you up when you have an low breath rate episode. This tries to prevent your blood oxygen volume from dropping to dangerous levels.
|Low breath rate alarm sensitivity||
Set sensitivity for the low breath rate alarm.
Turn on your oximeter
If you have an older (non-BTLE) oximeter, pair it with your phone using the system bluetooth settings.
If you have a newer (BTLE) oximeter, do not pair it.
Connect the oximeter to the app by tapping Settings → Wearables → Pulse oximeter (Bluetooth)
Now when you start sleep tracking, Sleep will connect to your oximeter to gather SpO2 and HR data.
Make sure the wearable is connected properly, and corresponding option is enabled in Settings → Wearables → Use wearable.
Enable SpO2 data gathering in Settings → Wearables → Pulse oximeter (Wear Os…).
The app can ONLY connect to the stress locator when it’s first paired with the phone (or removed and re-paired) and no other app has been used (e.g. StressLocator app).
2017 and beyond
The app can only connect to the Oximeter when it is NOT PAIRED to the phone.
