Once readjusted it was no problem. I had to get up a couple of times for my dog, due to the storms last night. But it (sensor) seemed to work as specified. Overall I think it worked well overall. The data will tell the story. I’ll repeat again tonight. ### 5/5 — Solid App *2026-08-13, version 6.1.0* Instructions were easy to follow. They gave step by step instructions. Video was clear. So easy even an 80 year old was able to follow successfully. ### 5/5 — Sleep Study in my home *2026-08-12, version 6.1.0* I recently was sent to a Pulmonologist For Sleep Study. I fully expected to be going to some clinic and having to stay overnight. However, this office has a much better plan. They sent me a test that I can test at home, it was a small gadget that I taped to my finger and it was not a bother at all. There is an app connected through my phone and that’s how I turn it on and off. I would not pass this up if you have to take a sleep test. ### 5/5 — Night owl *2026-08-12, version 6.1.0* It was very easy to use and that was very helpful ### 5/5 — Great!!! *2026-08-11, version 6.1.0* Very easy to use. ### 5/5 — First nite *2026-08-11, version 6.1.0* Actually slept pretty good because the test is not evasive. Original sleep test 20 years ago was terrible. Wires attached all over. This test did not bother me at all. ### 5/5 — Easy *2026-08-11, version 6.1.0* This is way better than wires everywhere!! Super easy! ### 5/5 — Clever Solution *2026-08-09, version 6.1.0* I have participated in three prior sleep tests. With the use of some clever technology we now have an effective, simple to use, in home testing system, to confirm sleep apnea. Congratulations to the smart entrepreneurs that invented and developed this excellent system. ### 5/5 — Great Experience *2026-08-09, version 6.1.0* Night Owl arrived in a timely manner and was easily utilized. I would recommend it to everyone! ### 5/5 — Good Night With Night Owl *2026-08-07, version 6.1.0* Very easy to use and not complicated at all. Slept good with it. ### 5/5 — Sleep at home *2026-08-04, version 6.1.0* Glad this is a home test. Convenient. ### 5/5 — Levy *2026-08-03, version 6.1.0* Easy and simple to on ### 4/5 — Easy! *2026-08-03, version 6.1.0* This was way more convenient and easy to do. If I had any suggestions on how to improve I would suggest that the instruction sheet should to be rewritten to have more simplified instructions. ### 5/5 — So Easy *2026-08-03, version 6.1.0* I like that the test is very is to use instead of the band that would go around your body a few years ago again very easy and convenient ### 5/5 — Surprising a good night sleep *2026-07-31, version 6.1.0* I was very surprised because I never slept all these years without the CPAP mask over my face ### 5/5 — Review *2026-07-29, version 6.1.0* I am not a techy type of person and originally didn’t want to use this form of monitoring by using an app because usually something goes wrong or doesn’t set up right I original wanted an in office visit however like all other doctors I couldn’t get one for months and months so I opted to do this NightOwl app and thankfully it was easy to do. The instructions were simple steps, short and easy. Thankfully, something simple for a change. ### 5/5 — Easy and better *2026-07-29, version 6.1.0* Thanks for the useful little machine. ## Most critical reviews (10 lowest-rated) ### 1/5 — Be prepared to waste time! *2026-08-21, version 6.1.0* Have been trying to get this app to work for two days and have been coordinating with my healthcare provider. It keeps saying that my birthdate is incorrect despite the fact that it’s the same birthdate healthcare provider has on file not to mention the day that I was born. Have deleted and reinstalled the app multiple times. Have tried different activation methods. App seems buggy to begin with and don’t really feel comfortable with it on my phone anymore ### 1/5 — Keeps resending devices *2026-08-10, version 6.1.0* I called about a second unit they just shipped and we didn’t ask for. Poor customer service. Of course I’ll ship it back, but then I’ll have to fight their billing. ### 1/5 — Buggy *2026-08-03, version 6.1.0* I kept getting a pop up saying Error - Sorry there was an error! The app lost my personal details. I had to choose my DOB 1 day in advance to get the right date to show in my personal details. I couldn’t start the recording because of the error. I deleted the app and downloaded it again and was then able to get my details in and record my sleep. It wasted an hour of my evening. ### 1/5 — I can’t get to the testing part! *2026-07-03, version 6.1.0* I keep trying to set it up for the night, but it keeps shutting down when I press “continue” or my “birthday bar”. ### 1/5 — Stops working after 2 nights *2026-06-26, version 6.1.0* 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. ### 1/5 — return before opening *2026-05-19, version 6.1.0* this thing is a scam. with insurance the little device that pairs with this app is 200 dollars. you don’t even get a copy of the results, gotta book another costly appointment with the doctor. should have saved the money and just gone with a pokemon sleep device, at least that provides me the results. ### 1/5 — App would never open *2026-05-08, version 6.1.0* Deleted it multiple times and restarted my iPhone multiple times. Zero success. ### 1/5 — Buggy Mess *2026-04-15, version 6.1.0* Constantly gets stuck in loops saying it is uploading logs, then a toast notification says the upload was successful, but the main app says it is still uploading and gives errors. The only way to clear this is to reinstall the app and re-enter the activation code. ### 1/5 — Exploitive billing *2026-04-07, version 6.1.0* I was sent the device with instructions to complete a three-night test. I completed the first night, but my doctor then adjusted my medication and advised me to wait before finishing the remaining two nights until I had time to adjust. During that time, VirtuOx processed the data from the single completed night and billed $250. When I called to discuss the situation, I spoke with Abigail, whose response came across as lacking empathy and condescending. I was told that if I wanted to complete the full three-night study, I would need to start over and pay an additional $250. If the test requires 3 nights study, why won’t the company wait for me to complete the three nights? Why are they rushing me to pay a bill just to get me to do the test again? I was disappointed there wasn’t more consideration. ### 1/5 — Notifications Never Stop *2026-02-18, version 6.1.0* This app constantly sends me the same notification every hour. I understand the sleep test was extended STOP THE CONSTANT NOTIFICATIONS ## Most praised reviews (10 highest-rated) ### 5/5 — Alfonso *2026-08-24, version 6.1.0* Es un estudio super lo cual te ayuda a saber que tan bien duerme o si tienes algún síntoma de falta de oxígeno ### 5/5 — Easy To Use *2026-08-24, version 6.1.0* Simple instructions and comfortable to wear. No issues. ### 5/5 — Easy to Use *2026-08-24, version 6.1.0* I thought the setup and use was very easy, Thank You. ### 5/5 — My First Night Owl,night *2026-08-23, version 6.1.0* SETTING UP WAS WELL EXPLAINED AND So simple. It was easy to record and not bothersome having it on my finger all night. I slept my normal pattern being in my own home environment .. Will share my second night soon I recommend this for anyone in need of a sleep study. ### 5/5 — Great experience *2026-08-19, version 6.1.0* Do much better than the strap on equipment and going in to the company where you sleep in their room and a strapped with their equipment. You have My vote! ### 5/5 — Great Experience *2026-08-18, version 6.1.0* Well designed app. Instructions very clear and videos very helpful.

I’m not sure why a couple hours and that’s all I could. ### 5/5 — NightOwl *2026-08-17, version 6.1.0* I like this concept of the night owl something new to me and I’m always willing to try it. Thank you. N ### 5/5 — NightOwl Sleep Study Review *2026-08-16, version 6.1.0* I had a very positive experience with the NightOwl Sleep Study. The device was small and attached easily to my left forefinger using the tape provided. It was simple to set up, comfortable to wear throughout the night, and did not interfere with my sleep. One of the biggest advantages is that you can complete the sleep study in the comfort of your own bed rather than spending the night in a sleep lab. The process was convenient, easy, and stress-free. I would highly recommend the NightOwl device to anyone who needs a sleep study. It provides a comfortable and user-friendly way to gather important sleep data from home. ### 5/5 — Easy *2026-08-15, version 6.1.0* No wires was a nice easy test --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
