Via Loïc le Meur comes news that Motion Based now has a Mac client up as a beta. It’s a plugin for Safari — and it lets Mac users upload GPS data from GPS devices to the Motion Based site, just like PC users. There they can store and analyse their sports outings. Remember, though, that for companies other than Google, beta means beta.

(“MotionBased is a web application that translates GPS data into functional analysis and online mapping for endurance and outdoor athletes.”)
