What a difference from having wires taped all over your head and everywhere. Just a little tiny thing taped on your finger. My sleep was not impeded by this at all, and it was very easy to do.
★★★★★Margie Trotter· Sep 26, 2026
It was good and very comfortable on my finger no stress putting it on my finger I like this system, and I put on again to night if I ever have to do this again I chose this method.
★★★★★Melessa West· Sep 27, 2026
I didn't sleep very good personally but Night Owl was easy to use.
★★★★★Milinda Greer· Aug 30, 2026
Sooooo easy, love it was a home test, and I could sleep in my own bed.

The app works well as does the Diagnosis the SEROUS issue is that your physician WILL NOT get that information for over 15 weeks. If you do indeed have severe sleep apnea this increases your chance of heart attack, stroke and yes death by a significant margin. So no I do not recommend this product whatsoever. If you value your life, literally, I would highly recommend you choose another app that won't put you at risk.

We code reader doesn't work and the company just sends you a download with no code
★★☆☆☆Graeme Lock· Sep 2, 2026
Useless and intrusive. For someone with anxiety/sensory issues, having something on your finger does not allow a comfortable sleep. 1st night the test failed for no good reason. 4th night the upload just wouldn't process and the app became unusable. So four disturbed nights using this, for only two results. And the post sleep surveys are terrible - how could you possibly know how many minutes it took you to fall asleep? Thinking about that gives anxiety and makes it even harder to fall asleep!
