  1. 4/5Very helpful, but please save graphs

    Love this app for tracking my SpO2 while sleeping. I get a clear picture of the difference between wearing my CPAP and not. However, I wish it would save the information in the graphical form it displays for each 24-hour period. This would allow me to access graphs from previous nights to show my sleep doctor.

  2. 1/5Does not work

    I downloaded this to get blood oxygen on my Ultra 2. It does not warn you that this does not work on this watch. I could not test it first, it required a purchase which I purchased the lifetime. Well you got my money and it does not work. The funny part here is after you install, you have to download the stock blood oxygen app, then sync it. Well if it didn’t work on the original app why would this app work. This seems like a major scam. I bought the app because the original app didn’t work not to get an app that talks to an app that doesn’t work. I want my money back. The seller finally came back saying sorry, they don’t do the refunds. You have to go to apple to request this and by the way if your more than 1 week past you probably won’t get a refund. Nice guys, you waited until over a week to tell me this. If I could give you zero stars I would give that to you.

  3. 5/5Life saver for hypoxemia

    I had bought Apple Watch to use the oxygen level measurement as I suffer from hypoxemia, I was diagnosed some weeks back. The app sends push notifications on my iPhone of my oxygen levels and can be configured to send low below 95% notifications which are handy at night as if I wake up in the night I can instantly see the notifications from outside which alleviate a lot of anxiety. Excellent service from the developer too, responded quickly to my question on hrv.

  4. 5/5Great. Love there Apps

    I found this app and love it. It is great for keeping track of my oxygen levels and my blood pressure. Currently I only use it for recording blood pressure as I don’t have a way to monitor oxygen levels. I am hoping eventually to get an Apple Watch. I was using there BP monitor app but this app adds the oxygen levels and blood pressure. I am a asthma patient and want to use the breathing exercise they have. Only thing lacking is a way to backup and restore data.

  5. 5/5Life saver for me and records HRV alerts too

    I suffer from asthma and this app's timely notification are something I was looking for and now totally rely on. Throughout the night, levels are recorded periodically. A surprirse was HRV levels are also recordrd and general stress levels logged that I refer more than a few times daily. A huge shouts out to the developer for this.
