血氧 血氧檢測

The developers actively work on this app, and it shows, the application is much better now than even a year before. Now it is my go to application for monitoring heart rate variability. Readings are quick and accurate, analysis are spot on.

The blood oxygen levels is good avocation for me

Try to get blood oxygen down, $30 later does not work. What a waste of money and time.

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.

The app doesn’t work. Don’t waste your money. Hopefully I can get my money back.

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.

This app was great because I could see my O2 level at a glance. Now all I see is them trying to get money for a premium subscription. Not worth it!!

The latest update took my premium access away.
