In March this year at SXSW, when Foursquare launched foursquare 3.0 it added some excellent new features which made the popular geo app even more compelling. Among these is a revamped leaderboard which shows how many points you've earned in the past 7 days compared to just your friends. The other one is a new Explore feature that gives you recommendations of nearby places to eat, drink, and shop based on where you are and your friends' past check-in behavior.
Also, available now the new Leaderboard, and post-check-in leaderboard information.
Now these features, along with the information users get after they check-in, are available to outside developers via Foursquare's API.
"Each of our mobile apps is built on our same API, so we're super excited to finally put all those tools in the hands of external developers. If you're a developer and your app already uses the foursquare API, Explore is a great way to find places to go. Imagine your dating app with suggested spots, or your food app with tailored restaurant recommendations. And, with the leaderboard endpoints, you can now build more of the core foursquare experience into what you're doing," foursquare stated.
