    This is a great DEVELOPMENT DEVICE but it is nowhere near ready for use "out of the box". The device presents a WiFi access point. You can login to this access point and then load the device's webpage at http://192.168.4.1 . It shows heart rate, which is kinda accurate, sometimes, in certain cases. And there's no code at all that does any SpO2 sampling or calculations And you have to open the back to access the micro-usb charging and programming port. But if you're into this sort of thing it may provide useful to you.
