About this app

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.

The setup instructions are okay. Only I would add, do not put the phone in the bottom sheet pocket. Although closer to the Night Owl device on my finger, I believe it caused zero results. I think it needs to lie on a flat surface. Applying the tape can be tricky, too tight and it won't read. Not using oxygen and CPAP was very difficult for me. For me, it was better to give this at-home test a try versus driving an hour and a half to the Sleep Clinic.

Smooth operation the first night. I tried a different sleep study machine that was not disposable prior to using this and it had many issues, resulting in no sleep study data. This was very easy to operate compared to that. Just make sure you allow the app to run in the background (you will be automatically notified during the setup process if you need to allow this on your phone).

Not a good app for uploading sleep data. I have been using the app for a week while trying to complete a four-day sleep study. The device connects through the app each night, but in the morning, it fails to upload on most occasions. The only way to stop the upload attempts is to remove and reinstall the app, and then redo the sleep study. It is a very easy app to navigate. This is why I have given it two stars. I reached out to NightOwl; I received a basic reply that it could be my connection.
