Yelp is continuing it’s location-oriented dominance, now boasting close to one million downloads of their Android app since last December when it launched. Their number of active mobile users is growing by 50 percent each week, and now stands at 2.5 million. A large portion of this number does come from their iPhone userbase, but the recent addition of check-ins and more Foursquare-like elements such as badges is in large part responsible for the rapid growth of Yelp on all platforms.

Mobile use still only accounts for 7 percent of the 34 million total users of the social rating and local search service between apps and the Yelp website, but those using a smartphone make up 27 percent of all searches queried. Yelp’s mobile presence is slightly greater than Foursquare who they now directly challenge on the check-in front. Do you count yourself among the millions using Yelp, or is another location-based social service the only worthy of any storage space on your phone?
