About NightOwl Companion

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. Disclaimer: This app may provide information from external medical devices. Before making any medical decisions based on this information, read the device instructions carefully and speak with your healthcare provider.
