Oximeter

1. What it does

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.

2. Where to find it

Settings → Wearables → Pulse oximeter

4.1. How to set up

  1. Turn on your oximeter

    1. If you have an older (non-BTLE) oximeter, pair it with your phone using the system bluetooth settings.

    2. If you have a newer (BTLE) oximeter, do not pair it.

  2. 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.
