NightOwl Companion

The NightOwl Companion app allows you to interact with the NightOwl sensor.

This app will allow you to interact with the NightOwl sensor, which will check whether you suffer from sleep apnea by measuring signals from the tip of your index finger with a small light sensor that connects wirelessly with your smartphone.

You will be asked to sleep with this sensor for a number of nights. Setting up the test is very straightforward and will only take a few minutes of your time.
