For anyone who likes a nice structured itinerary for their weekend Vegas bender, TripIt is a handy app that combines flight, public transit, hotel, and restaurant info in to a tight little scheduling interface. And to make said interface even more tight, TripIt has revised the UI in the latest build. Well, at least some of the UI - from what we can tell, you'll only see the spiffy new blue-tinted screens if you're using a phone.
Field Trip is an oddity in Google's app lineup. It comes from Niantic Labs (the people who went on to create Ingress), looks fantastic, and it's made for a very specific kind of user. The app highlights attractions of historical, cultural, and entertainment value in your immediate area, using GPS and services like Thrillist, Zagat, and Cool Hunting to create a "hyperlocal" experience. Of course, any travel app is only good if it works where you are, which was a sticking point for international users.
