BLE Heart rate graph in javascript

HR – Plot multiple bluetooth heart rate monitors on a graph

Here it is if you want to try it.

It is just a html page with javascript. No cookies, server side anything, tracking, cost or adverts.

It looks a bit like this with 3 devices all connected at once:

Heart rate graph screen dump

Heart rate graph screen dump

It can handle the ”upload” of multiple gpx track and plot the heart rate from those as well as map them. Again nothing is actually uploaded – it is all browser based javascript. Not very pretty either and a bit buggy..
