In 2014, Foursquare split into two apps, moving the social components to an app called "Swarm". With the removal of the social interaction from Foursquare, the number of active users started to diminish. This resulted in fewer new reviews.
Rather than provide a long list of attractions, TripExperts only show the best attractions in a specific area based on expert reviews. This makes it much faster to find quality attractions, rather than searching through hundreds of less interesting options.
Along with having a photo gallery, each attraction has a small description, plenty of reviews and a map. The "Tribe" feature tells you what type of travelers enjoy that attraction the most (Outdoor Enthusiasts, Local Culture, Adventure Travelers etc.).
Fodor's Travels makes it easy for you to scan a destination and see if it's a good place for you. They cover top attractions, when to go, travel advice (such as health and what to wear), and have a photo gallery.
