Foursquare announced on its blog today that it had exceeded 10 million users, while breaking down by category which brands were in the top 3 on the mobile app.

For apparel, Old Navy, H&M, and Victoria's Secret charted the highest, while on the retail front Target, Walmart, and Macy's got the most check-ins. Convenience stores 7 Eleven, Circle K, and Wawa lead their category, while Bank of America, Chase, and Wells Fargo had the most check-ins among financial brands. New York-based Foursquare also broke out a home furnishing category, where Home Depot, IKEA and Lowe's are the most popular.

Those brands and countless others have begun marketing on the geo-social platform in the last 18 months. They typically offer discounts or free merchandise for check-ins, rewarding "mayors" of their locations for consistent patronage. Foursquare suggests that competition for the mayorships is fierce; it says more than 78,000 of them change hands every day.

Accenting how the geo-social platform has become more mainstream, Foursquare also noted that there have been 4.7 million check-ins for businesses located on Main Streets in U.S. cities. The company's blog also suggested that the app was gaining traction in Japan and Germany.

Two-year-old Foursquare's ascent to 10 million users has been impressive. Only 15 months ago, it had 500,000 users.
