Pew Study: 18% Of U.S. Smartphone Owners Use Check-In Apps

According to a new study by the Pew Internet & American Life Project, the popularity of check-in apps continues to grow, though it still isn't quite mainstream yet. Pew's latest survey found that in February 2012, 18% of U.S. smartphone owners over 18 used geosocial check-in apps like Foursquare. That's up from 12% in May 2011. Even among adults who said they own a cell phone but not a smartphone, 11% said they used check-in apps. This means that 10% of U.S. adults (including those who don't own a cell phone), have now used check-in services at some point in the past.
