Oximeter monitors your oxygen and heart rate levels. You need a compatible device - buy it here.
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.
Settings → Wearables → Pulse oximeter
Enable the feature
|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 Sleep as Android → Settings → Wearables → Pulse oximeter
Now when you start sleep tracking, Sleep will connect to your oximeter to gather SpO2 and HR data.
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.
