User Reviews

Users like the app's look and watch integration, but many report it doesn't measure SPO2, uses estimations, and has reliability issues. The subscription model, upselling, lack of support, and frequent prompts worsen the experience, leading to frustration despite convenient design and sleep data.

Pros

Clean design and easy-to-understand interface.
Works well with Apple Watch and keeps all data in one place.
Includes sleep information and broader health data, not just oxygen readings.

Cons

Does not actually measure blood oxygen saturation; relies on questions/heart rate/breathing, making its core claim misleading.
Premium subscription is expensive with aggressive upsell prompts and reports of poor developer support and refunds.
Reliability issues: readings stop recording, there are long gaps, and data may only appear in Health app instead of the Blood Oxygen app.
Apple Watch integration is limited; the watch readouts do not provide real SPO2.
No free trial and frequent pay prompts, making it hard to test before paying.

Recent reviews

RN REVIEW: I downloaded this app because it was supposed to be able to use my watch to measure my O2 saturation. I was immediately hit with an annual fee of $25. In order to use it, at all. Because it said it was compliant with the Apple Watch I bought it. First, it doesn’t use my Apple Watch to measure, it uses my finger over both the flash and the camera at the same time which is not easy to do. And it doesn’t even measure my oxygen. It only measures my heart rate, then I have to do this weird tapping thing to measure my respiration rate. Then I have to ANDWER A QUIZ and then your oxygen level is fine based on your results OF THE QUIZ! As an RN I am flabbergasted that it thinks asking me if I am stressed can determine if I have a low oxygen level!!! This is DANGEROUS!

I like the app as it lets you know ahead of time to rest if your pushing to hard. Also it teaches you about other heart factors you should be aware of as well.
