Fling – Prefer your dating experiences in apps? Fling is a mixed dating site (meaning it’s for both longer term relationships as well as the one night hookup) that also has a downloadable app. On the outside, Fling is a site that covers all the bases in a rather general way. There are the usual singles who are looking for love, but there’s also the swinging couple crowd, the guy on a business trip looking for some ass, and the cheating husbands and wifes. It’s also one of the truly free dating sites. While most of the online dating programs out there only let you connect with members once you’ve signed up for their membership, Fling lets you get connecting right off the bat. Up sides to their payments are a few additional options like profile promotion. Not too shabby!
