In case you were wondering which mobile app offers the best cruising ROI, this handy chart might help you decide who wins the war in Gaydar vs. Grindr. (Though the Dallas Voice doesn’t say so, the chart was prepared in-house by Gaydar’s publicity team as a marketing tool.) Having already duked it out with Manhunt, Gaydar is now throwing down against Joel Simkahi’s start-up that’s done a fine job at owning the buzz surrounding gay chat apps. Putting its six million members on the mobile market, Gaydar enters the field and immediately slaps down the competition — if this were a numbers game. But in two seconds other apps’ supporters will be on this post saying that if your goal is quick ass, you’re best bet is probably Grindr. (Or West Fourth? They’re not even on the chart.) The one advantage Grindr definitely has over the Britain-based Gaydar to compete in the U.S. market? Measuring how far away your next yank is in feet and miles, not meters. Of course, choosy guys just looking for choosy friends choose Fab.
