If you can’t beat ’em, join ’em. As the mobile check-in game get more popular — and thus, more annoying — with each passing day, the new breed of LBS services must find new ways to fight for users. But can’t they all just get along? Gowalla seems to think so, and with its newly updated iOS application, the company hopes to keep users immersed by removing the need to switch apps if they choose to check-in with multiple services. Gowalla 3.0 allows users to irritate their friends like never before by allowing them to check into Gowalla, Foursquare, Facebook, Twitter and Tumblr simultaneously. Other additions in version 3 include better Retina Display support, a tweaked UI and bookmark support for visited places. Gowalla might not be the biggest LBS in the bunch, but by unifying the check-in process it hopes to become a one-stop shop that will simplify check-ins for active users.
