magnetospeed chronograph

[rdog52]

Has anyone used the XFR (?) accessory for the magnetospeed? Did you get the app to work as I could not get the app on my iphone to sync with the little black box when I was piddling with it yesterday here at the house.

I have it and also have occasions that it will not sync. I don't understand why. Sometimes just a simple unplug and try again works.
