Above is the screen shot from an email I received from Qardio regarding their Blood Pressure kit.  The bluetooth enabled blood pressure kit is fantastic. It works on Android too.

But now it can work via your Apple Watch. Neat. For sure. Pointless too.

Surely it makes more sense to use the larger screen on your phone than the Apple Watch. Also,  if you have many apps running on your Apple Watch, your battery will be dying really fast.
