I might be wrong, It’s not like measuring blood science is rocket science. You can have an analog bracelet and pump, or for cheap buy an electronic one that you can operate with a single button.

I’m sure this will have its uses for people who are on the go a lot, but measuring at home has always been an option. If anything the advantage here is to measure on the go.

Wait, this looks very nifty. But digital blood pressure monitor with air pump is quite cheap nowadays and very easy to get one.

Also this seems to be the extension of measuring heartbeat with camera + flashlight that was out there like 10 years ago (you measure it by placing your thumb over your phone’s camera). I wonder if eventually smartphone maker would just have it built in.
