There was a similar app during the check-in app craze (where a half-dozen competing apps existed) but that didn't stop Foursquare from eventually winning the space (even though it was arguably not the best of the options).
They invented the concept, so far as I was aware, in the form of Dodgeball. Foursquare was just their relaunch of Dodgeball after the failed Google acquisition.
