Google has announced on Google+ that they've added some new Glassware to Google Glass, namely TripIt, Foursquare and OpenTable.
I personally have been using a third-party Foursquare app for a while and love it, I believe the official Foursquare version is very limited but probably solid enough. I plan on playing with it over the next few days.
