Ever since it updated its app this fall, Foursquare users were interacting 60% more often than they did on previous versions of the app. Foursquare users also now spend 30% more time on the app.
Here's how Foursquare accomplished the feat: The team discovered it could use a technique called "geofencing."
Geofencing means Foursquare can send your phone a notification about a venue you'd might like to go to whenever you're near the place.
It seems to be working so far. But some people are quite skeptical. Ben Lerer, the CEO of Thrillist, isn't quite convinced that this new hack will be a game-changer for the startup.
"It's a really compelling technology that [could] help them get bought by Google or Facebook or somebody else," Lerer told Wired. But he still doesn't think it "will explode their numbers."
