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. Version 1.09 expands to more than 80 countries with support for over 30 languages.
It would be nice if the boys and girls at Niantic told us which countries and languages the app supports, but alas, no dice. (International readers, feel free to sound off in the comments.) But if you should come across a featured attraction written in something other than your native tongue, Field Trip will now use Google Translate to automatically generate a more comprehensible version. Your mileage may vary when it comes to local entries, especially in more rural areas.
At launch, Field Trip was recommended only for smartphones. The interface is still just one panel (as opposed to the multi-paned UI that most tablet-enhanced apps have) but the "recommended for smartphones" warning has disappeared. Take that as you will, I suppose.
