Many dating services now offer their apps as the only option for connecting with other users.
Among the most popular is Tinder, a relatively young dating service that made swiping right and left on potential dates' photos the standard for saying yes and no.
About 39 percent of users in the New York area said they wanted a long-term relationship, followed by 30 percent looking for casual dating and 16 percent looking for a casual sex.
Los Angeles, on the other hand, appears to be hook up central, with 34 percent of Clover users saying they wanted something much less committed.
By the summer, between 60 to 65 percent were opting for mobile access.
