Foursquare today announced it would be unbundling its location-based service into two separate mobile apps; one will be called Swarm, while the other retains the original Foursquare branding.
The idea is to break its business in half. Foursquare started out as a check-in app, allowing you to easily broadcast your location to friends and family. This will continue to exist under Swarm, a new Android and iOS app due in the coming weeks. A version for Windows Phone will follow shortly afterwards.
