Perhaps it's semantics, but Glympse reports your current position and speed (possibly based on the time between successive positions) but does not save all these coordinates for a ride on the phone or web and does not generate a track you can view or file to download. It only shows current position, hence I say that it doesn't record tracks or data.

I have several Garmins (non 810 or 510 versions) and they do what I want, which is record tracks and ride data creating files I can save, view or further analyze. Glympse serves a different purpose, to report my current position to interested observers (spouse, next of kin, whatever).
