Comments on NightOwl Companion for Android

★★★★★ Peter Barnes · Jun 23, 2026

To God be the glory, it was very easy to set up, very easy to use on finger.

★★★★★ Leonore Marchand · May 28, 2026

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

★★★★★ Art · Jul 3, 2026

Much, much better test experience than the standard sleep study in a facility that involves a lot of wires and cable connections all over patient's body. The Night owl companion test is done in the comfort of my own personal bed at my own residence. Very practical, convenient and easy.

★★★★★ 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!

★★★★★ Lori Hutch · Jul 2, 2026

This was a much easier home sleep test experience than I've had in the past. The directions are very clear and easy to follow with the app

★☆☆☆☆ Buddy K. · Jun 9, 2026

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!

★☆☆☆☆ Jeffrey Meyer · Jun 30, 2026

Nothing but troubles with this app. It can not scan its own I'd code. Scan fails. After one night's use, I can not use the app again. I get an error "can not upload data".
