About this app

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.

The device is fine. However if your internet connection is weak the test will fail. The company as whole is not trained to communicate with non technical people. Like Ismael said the last step in the setup is confusing. It would not be hard to put the record button in a more intuitive place. The gesture to scroll up means something else to my phone which adds to the frustration.

The UX is frustrating because it takes SO many steps to just start, and then the last screen has so much text that the "Start Recording" button is hidden away and there was no indication that I had to scroll down to find and press it... So basically I slept with my finger wrapped up for nothing! I'm so upset I really hope they fire their designer. I'm serious. I suppose is still better than a real sleep test.

I was supposed to do a 2 night test but was only able to successfully do 1 which was the very first night. On the second night, it failed to record anything. Tried it again on the third night for a second test, it won't connect to the app any longer and the app shows instruction now for an entirely different device. Contacted provider for help and was told to just uninstall/reinstall. Tried but failed everytime. Fourth night same. Fifth night, same. Sixth night, different device, same. I'm done.
