Combine this with magic Uploaders and the info that it provides can literally help improve your health! Knowledge is power and this info is simple to get with these products. ### 5/5 — Great companion app for the O2 ring *2023-05-29* SleepO2 is a companion app for the O2 ring, not a standalone app. The O2 ring is a blood oximeter that you wear on a finger overnight while sleeping. It measures your O2 level, heart rate, and movement throughout the night. In the morning when you wake up, as soon as you take off the O2 ring, it uploads all the data to this app. The O2 ring and this app are especially useful for people with sleep apnea on CPAP therapy, or people who think they might have sleep apnea. The app presents the data in easy-to-read charts. If you don’t know anything about how sleep apnea impacts O2 levels and the heart rate, you have a little learning to do - but it’s not hard, promise! With the charts in this app, you can quickly get a sense of how well your CPAP therapy is working - or not working - and can make adjustments to your machine settings accordingly. For example, if the data shows frequent drops in your blood O2 levels, accompanied by spikes in your heart rate, then you need to go into your machine settings and turn up the pressure a bit. If the data shows consistent high O2 levels (96% is very good) and no spikes in your heart rate, then you try reducing the pressure setting of your machine a bit, which makes CPAP therapy more comfortable and tolerable. Importantly, if your O2 levels are low or you have frequent drops in O2 levels, that’s a sign you need to talk to your doctor about next steps, because if untreated you are at high risk of all kinds of serious health problems. I find the app super easy to use. I went to the developer’s YouTube channel (“CPAP Reviews”) which has easy-to-understand explanations of all of this stuff, including the O2 ring and the app. The best defense against health problems from sleep apnea is being an informed patient, and I’ve found the developer’s YouTube channel to be an extremely helpful and easy to understand information resource. And my O2 ring and this app are a big part of my therapy regime - they help me understand how well my therapy is working, so I can get good, restorative sleep, which reduces my stress level, blood pressure, and risk of stroke & diabetes. **Developer response:** Thank you for the wonderful, in-depth review. Much appreciated :-) Uncle Nicko ### 5/5 — Sleep apnea *2023-05-02* Having the data collected from SleepO2 and then synced with sleep HQ has helped me understand my sleep apnea problem so much better. Thank you guys for the app. So far everything has worked perfectly. **Developer response:** Hi Cindy, thanks for taking the time to review our app. We really appreciate it. Best wishes Uncle Nicko ### 5/5 — Love the SleepO2 app and SleepHQ O2 Ring! *2023-01-14, version 1.1.2* Thanks Uncle Nicko and Adam for this great app and O2 ring. It gives me advance information for my sleep apnea therapy. I never knew that I should keep an eye on my blood oxygen content and heart rate. It was extremely easy to set up! ### 5/5 — Great app! *2023-01-01, version 1.1.2* The sleep O2 app is so easy to use and integrates well with SleepHQ. Thanks! **Developer response:** Awesome! Thanks for sharing your review. Cheers ### 5/5 — Works great with Sleep HQ *2022-12-22, version 1.1.2* One of my sleep apnea issues is low blood oxygen. Using an O2 ring and this app with Sleep HQ I have been able to adjust my therapy and increase my blood oxygen levels. I feel so much better. This has been very helpful. **Developer response:** Great to hear it! Thanks for sharing your 5 star review. It's much appreciated. Cheers Uncle Nicko ### 5/5 — Terrific integration! *2022-12-22, version 1.1.2* This is a great app to gather data from your O2 ring. Not only that, it integrates with the best sleep apnea data software out there, SleepHQ! Highly recommended! I never leave reviews, but it was a no brained to write this one. **Developer response:** Hi there, we really appreciate your kind review. Thanks for taking time out to share your feedback. All the best Uncle Nicko ### 5/5 — Excited *2022-12-20, version 1.1.1* Found Nicko's channel. Been watching and very impressive. Giving his stuff a hard try. All seems very logical and better than what Resmed and my air provide. Getting a ring and following his advise. Thank you Sir for your efforts **Developer response:** Thank you my friend. Your review is much appreciated. Take care Uncle Nicko ### 5/5 — Integrates with SleepHQ, not Apple Health *2022-12-17, version 1.1.1* This is a companion app for the O2 Ring you can buy to easily upload heart rate and SpO2 data to SleepHQ. If that is your goal, this is a wonderful app, and lets you zoom into graphical data on heart rate and SpO2 as needed. This app does not currently write data to Apple Health, which I think would be a very useful addition to the next version. That way, the same heart rate and SP02 levels could be used by additional sleep monitoring apps. **Developer response:** Hi Mike, thanks for your wonderful review and great suggestions. You will be happy to know that the app now writes data to Apple Health and can also read sleep stages and sync them with SleepHQ. All the best mate Uncle Nicko ### 5/5 — Worked quickly *2022-11-29, version 1.1.1* By the time I connected to phone then logged into sleepHq on my laptop the data was there. Nicely done **Developer response:** Wow! That's great news. Thanks for the 5 star review!
