“The fun way to find people like you,” LOVOO is one of the most popular apps for flirting, with more than 50 million members. You can register, upload and send photos, and chat with like-minded singles all without having to spend a single penny. Perhaps the coolest feature on LOVOO is their live radar that shows what’s happening in your area and who’s participating.
If you don't have the patience to weed out matches that are explicitly looking for a no strings attached hookup, a quick search on FriendFinder-X will probably make you pretty happy. You can search for potential matches using filters that range from proximity, sexual preferences and even cup size. Too lazy to search? The app has a list of compatible profiles sent to you for your consideration.
