Customer Reviews

Great app - very accurate not 100%

I just got my stats today and I ran multiple tests. I would say this app is 80-90% accurate but these percentages are unconfirmed. Tomorrow, I will confirm these numbers and provide much better feedback. Honestly, I'm a hardcore asthmatic and being able to just download the app with no additional add-ons was amazing and extremely convenient. Great job! I'll update with better or worse stats tomorrow. But I'm pretty sure that I'm right in the ballpark!


Last week I had appointment with my pulmologist , I asked her if she had heard of this app, she had not and expressed her doubts about it's accuracy. We compared the app with her equipment and it was spot on. We were amazed and she said she would start recommending the her patients with iPhones use this app.

Small fingers are a problem, but like its accuracy

Pulse & oximeter match well my other type of pulse oximeter results. My only difficulty is that I have very small fingers so it is hard to easily cover the camera plus light at the same time. Otherwise I like it.
