A new Pew research report reveals that while 35 percent of U.S. adults have apps on their cell phones, only 24 percent actually use them. “The Rise of Apps Culture” released Tuesday (Sept. 14) by the Pew Internet & American Life Project and Nielsen also shows that app use scores at the bottom of a list of what people do with their phones, just 29 percent. Taking photos is atop that list, at 6 percent . Other cell-phone uses include texting, 72 percent; accessing the Internet, 38 percent; and sending or receiving e-mail, 34 percent. Games, news/weather, and mapping apps are most popular. The research was conducted via a telephone survey of 2,252 U.S. adults age 18 and older between April 29 and May 30, 2010. The sample included 1,917 adult cell phone users, 744 of whom were contacted on those phones. The 46 page-study is online here (PDF).
