The Field Trip app by Google looks for sites of interest around you, based on categories you select and your location, and it pops up cards on your phone when you're near something interesting. If you're driving and have a connected Bluetooth audio device, you'll hear the alerts instead. Field Trip taps into recommendations from travel and lifestyle publications, such as Thrillist, Zagat, and Sunset, as well as Songkick and Flavorpill for finding local music.
