My watch is not compatible and I wanted to check oxygen level while I sleep. Cancel my subscription please.

I can’t believe I just paid $30 for this. It doesn’t measure blood oxygen at all. It measures pulse and breaths per minute, then guesses whether the oxygen levels are normal or not. This is not even remotely helpful.

I stiill want BloodO2% and blood pressure on my watch without having to go tlo my iPhone tool. You’re getting close. 🎶🇺🇸

This is a scam I want my money back I have COPD and wanted to check my oxygen levels it does not even come close. You tap on the screen when you excel then it says you are ok. When I know I wasn’t. No test SCAM…

I have asthma and COPD. This does a very good job of helping me stay aware of my blood oxygen levels and heart rates. Keeps me out of trouble and helps my doctor know my actual status.

“Put your finger over the flashlight” ??? A flashlight can measure you blood oxygen levels

No O2 results. A scam

So you only check what the O2 is once or twice per night. Not enough for what I am paying for it. You should be checking it every couple of hours to get a good picture of what is going on. So if you don’t change that, I’ll be looking for a different app next time. UPDATE: Thank you for answering my questions. It helped me understand why there’s such a difference from night to night. And during the day. It only registers when there is no movement, every 30 minutes. Maybe they could have it check every 15 minutes to give a person, who moves a lot at night, a better idea of their night. 11/10/25….. it is not updating. I tried updating but it doesn’t do that either. Hasn’t updated for three days. 11/30/25…. I’m canceling my subscription. It does update. And at times it only gives a couple of checks a night. it seemed to work for awhile up until the last month. I need to find a better one.

I wanted to monitor my sleep apnea. The app description mentioned compatibility with Apple iPhone iOS 14.0 or later. So that answered my question and I paid for a one year subscription. When I looked for the results the next morning, there were no values for oxygen levels. It looks like my watch model was not compatible. I would like a refund, please.

Works about 20% of the time, and then only if I adjust the band to near tourniquet tightness.
