Apps may be the current buzzword among developers and phone manufacturers, but a new study from the Pew Research Center's Internet & American Life Project suggests that only 35 percent of U.S. adults have apps installed on their phones.

Of adults using cell phones, only 24 percent actually report using those apps—and another 11 percent have no idea if their phone is equipped with apps in the first place. That being said, overall use of cell phones has increased over the past few years, with 82 percent of adults reporting cell phone ownership; on top of that, some 23 percent of surveyed adults lived in a household with a cell phone but no landline.

"An apps culture is clearly emerging among some cell phone users, particularly men and young adults," Kristen Purcell, associate director for research at the Pew Internet Project, wrote in the overview to the group's report. "Still, it is clear that this is the early stage of adoption when many cell phone owners do not know what their phone can do. The apps market seems somewhat ahead of a majority of adult cell phone users."
