It turns out Foursquare's massive 5.0 revamp was just the start of the changes, as the location sharing app unveiled a new twist with the launch its Connected Apps platform. Available as a developer preview, it lets the makers of apps like Untappd, Instagram or The Weather Channel connect directly with the Foursquare app. Many apps were already connected via the API, and once users upgrade to the latest version on Android or iOS their checkins pull information from those apps into Foursquare itself. That means they get things like the weather forecast on their first check in of the day from The Weather Channel, see what songs their friends have shared at a particular location via Soundtracking or beer recommendations from Untappd. Developers can get all the info on how it works at the overview, the rest of us can see the list of enabled apps on the official blog post.
