I want to agree with tuxcrafter. I also bought the HxM Bluetooth HR monitor but I can't export the data to any service (only for HeiaHeia, but they only display max and avg HR). The data seem correct to me, the problem is that the gpx file do not follow Garmin standards (which are the standard for most services) on HR. It's a pity.

I am in BRazil and N9 is not available here
