Walking / Running

Because GPS doesn't exist on the device or currently supported via gps, The Amiigo likely uses your height to determine stride. Adjusting this will effect your calories burn so I'd track it seperately and calibrate it off amiigo get a closer to reality distance. Although I'm a little puzzled that with an accelerometer you can't determine this I'm not versed enough to prove that it's possible just to caliculate it from foot pod data.
