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.
★★★★★ 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
★★★★★ Victoria Watson · Jun 22, 2026
I love that you can do this in the comfort of your own home!! When I did a sleep study before, I had 1000 cords attached to me, and I knew someone was watching me all night. It makes it hard to sleep for sure!! This is more comfortable!!
★★★★★ David Willers · Jun 28, 2026
Very easy, just follow the instructions; super cool and will help with sleep information.
★☆☆☆☆ Connie Hall · Jul 8, 2026
Cannot get app to open correctly...keeps showing me three pictures 😒
★☆☆☆☆ 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".
