This app allows you to interact with the NightOwl sensor that measures signals from your index finger with a small light sensor to check if you have sleep-related breathing disorders.

You can set up the test in a few minutes using the in-app instructional videos. Wear the sensor for the prescribed number of nights to complete the test.
