Platform(s): Android, iOS
Noted for: Trover
Trover is the brainchild of Expedia founder and Zillow co-founder Rich Barton. The app itself is an image-discovery social network, allowing users to tag objects and activities from different locations. Users have added images of food from different restaurants, activities popular in certain areas and facts about local history. The concept combines the image sharing nature of Tumblr or Instagram with the localization aspect of foursquare or Yelp.
What's next: Trover went live for iOS in July and expanded to Android last month. The LA Times reported over 100,000 downloads from over 160,000 countries. The Trover catalog is expanding, with the highest number of discoveries currently in San Francisco, New York, Boston, Chicago, London, Paris and Hong Kong.
