Compatible with my device, super easy to set up and use, and so far it's been super accurate as well! I use it to test my total lung capacity as a free diver rather than using the exercises they show for various other things that it also would be great at. For the purpose of tracking my overall lung capacity as well as my overall ability to use that capacity it has been amazing! Seeing the results in real time on my phone tracked for me is great too, so I don't have to put them down somewhere!

I can't connect to the device using my OPPO Reno8. Been trying it for one whole night. When clicking connect device, no action was taken

Downloaded app, tried to register, and get response back in Chinese. No idea what it is trying to tell me but can't complete sign up, so can't log in.

Stores some data in the short term, but won't allow me to sign up and actually track my progress long term. It just loads forever every time I try.
