Can you do it soon as possible. Thank you. ### 1/5 — Junk *2020-07-06* Poor instructions and no diagnostics for troubleshooting ### 1/5 — Please address problem for a better rating *2019-11-20* I want this to work for me. My morning stats puts my score at 99%, high green, in the red to green color scale; however, my average oxygen level displays as being 88% with 7 oxygen desaturations as low as 83%. Clearly, my oxygen levels are not in the 90+% range all night as i believe it should be. Am I wrong or is sub-88% oxygen all night worthy of the app’s 99%/A+ grade? ### 1/5 — Buggy *2019-05-03* App display is not formatted to work on iPhone X /Xs/Xs Max phones. The zoom boxes at the bottom for time are below the “Swipe home” button making them inaccessible. As a result you can’t actually get meaningful data since it is stuck in the zoomed out view. Would be good if they had a way to export data to your computer. ### 1/5 — Doesn’t fit the screen *2018-11-20, version 1.5.1* Doesn’t work with iPhone X and buttons ### 2/5 — Works good but... *2019-05-21* The bottom graph does not show on iPhone. Can’t zoom, can’t print. ### 3/5 — display problem on iphone 12 mini, iOS 15.4.1 *2022-05-20, version 1.5.1* the snoreO2 page with the data detail display and the dashboard page both load a bit low on the iphone display, leaving the bottom part of the two pages off the bottom of the iphone display. the time selections on the data display page are not accessable. ### 3/5 — Iffy *2020-03-04* How is it my O2 drops have been the same the last four nights yet the tracking time has never been the same. ### 3/5 — Answers all my questions *2020-02-23* Cpap did not work it made mild apnea worse. I got dental device,slightly uncomfortable but i have adjusted it till it is stopping 98 % of events. No follow up or help from dentist btw. What goes on during sleep is such a mystery. A year ago on cpap forums people complained about lack of recording o2 monitor. This device along with excellent app solves this shows pulse, o2, activity, stores records on phone it has a low oxygen alarm you can set to level,it’s simple to use. It is worth the $150 for device app is free. Update does not work right with new iPhones Just got 11 and cannot control scale. ### 3/5 — App Compatability *2020-02-19* Love the product but the app is cut off at the bottom and unable to use scaling function. Need to fix the app for iPhone XR ## Most praised reviews (5 highest-rated) ### 5/5 — I love it! You’ll need Viatom O2 device to use the app *2020-06-15* Update the App !! ******************* If you were looking for a wearable device (pulse oximeter) that records your O2 overnight and gives you meaningful results, this is the device for you. Future software updates need a few tweaks: 1. Statistical data – histograms for oxygen and heart rate 2. Export data – I would like to import the O2 and heart rate data into Excel using a CVS file. 3. Better documentation on how the algorithm calculates the O2 summary score. 4. Better advertising on the web and Amazon - It took a little bit of research to find it (I had to go to Alibaba, Chinese Amazon) ### 4/5 — Apple health integration needed *2020-03-23, version 1.5.1* The app seems to work ok. But it has no compatibility with other Apple health apps and can not me integrated into the health dashboard. ### 3/5 — Snore O2 *2019-06-28* Works well but does not integrate with Apple Health. This is a major flaw. Makes the app destined to the trash heap unless it becomes integrated with the Apple Health app. ### 3/5 — Report Lacking *2019-06-17* The report does not give the Average Heart Rate. This is why I need it. The graph is OK, but an average, hit, and low heart rate display would be appreciated. ### 3/5 — Not all app options available on latest iPhone. *2019-03-17* I have iPhone XS Max and can’t see the bottom what looks like 4 buttons and another icon. It is cut off. I don’t know what they’re for but I would think if you say the app is compatible you would check layout on all devices especially as new ones are released. Might want to consider adding scroll bar to go down the side and ability to export entire history rather than one snapshot so it can be shared with the doctor. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
