Comments on NightOwl Companion for Android

★★★★★ Mitzi LaPaugh · May 27, 2026

Easy to use. I had no issues sleeping and couldn't tell the device was on my finger.

★★★★★ Leonore Marchand · May 28, 2026

The testing was done in the comfort of my home. Instructions were simple and easy to follow.

★★★★★ Berine Thompson · May 31, 2026

Great and easy! This put all others sleep apnea testers to shame. Now if only cpap treatment could be as easy as cpap treatment difficulties would be solved and more and more people requiring cpap would be more than happy to sleep with cpap without a problem and thousands of complaints due to the ongoing negative side effects to one's health, mental health and over all well-being would be eliminated for most. Thanks, Night Owl!

★★★★★ Suann Ditzler · May 16, 2026

Night owl is incredibly easy to use and so far has been the easiest sleep test I've ever taken. Very convenient use in your own home, and nothing more than a finger monitor. Software installs on your phone And your phone have to be within proximity to the sensor on your finger. oh have things have changed over the years! Such an improvement!

1st day 1st try, app says there is an error, wait for developer to fix. 1st day 2nd try, app said error and blacked out. 1st day 3rd try, it just wouldn't connect. Uninstalled app, reinstalled, still no-go. Unable to start testing for the night. Frustrating! 2nd day, all the same results and some new issues but still no-go.

Won't open! I have tried to install and delete 3 or 4 times, nothing! Three pictures telling you what the app will do. It just won't do it!
