Google makes every trip an adventure with their new app, Field Trip.
Field Trip is an app that will run in the background and notify users once they get near something of interest, whether it is historic places, recommended restaurants, or unique shops. Field Trip will help users discover new places in new towns or even undiscovered locations in your local town.

From The App Store description:

★ Discover thousands of interesting places/experiences that fall under the following categories: Architecture, Historic Places & Events, Lifestyle, Offers & Deals, Food Drinks & Fun, Movie Locations, Outdoor Art and Obscure Places of Interest around you.
★ Choose from three different modes to set frequency of Field Trip notifications. See “Field Trip” worthy places around you on a map, by tapping on cards in map view to pull up enthralling points of interest around you.
★ Go on a Field Trip while you drive. Field Trip can detect when you’re driving and automatically “talk” about interesting places and experience around you.
