User Reviews
Comfortable and a cinch to use. Doesn't get any easier than this.
First night sleep Using the machine on my finger was easy. Slept well didn’t know anything was going on while sleeping. This is much better than the sleep study center.
The survey was difficult because it requires exact answers and I can’t remember what happened.
I keep trying to set it up for the night, but it keeps shutting down when I press “continue” or my “birthday bar”.
Easiest sleep study I’ve ever done.
It’s very easy to follow the instructions
Set up was easy and it didn't interfere with my sleep. Often I will take a nap in my chair, wake up and then go to bed. For this test I just went to bed at a normal time. I have two small dogs that sleep on my bed and sometimes they will jump off the bed and later make a fuss to get back up. I don't remember them doing that last night.
No issues. Just follow the instructions and that is it.
I used this app and device but it stopped working and allowing me to record my sleep sessions after only 2 nights. Every single day I open the app it just says session recorded with the new date above it even though I recorded nothing for that day. The app is up to date and I’m using an iphone 17 pro max.
Convenient
If this thing works it’s better than having wires on your head and staying awake all night, nobody can sleep with all those wires all over your head.
I love the night owl it was comfortable and I forgot I had it on and I had a good night sleep.
