PURE is specifically for hookups and nothing more -- everyone on the app is down for anonymous sex. You dont need to reveal too much about yourself or use your phone number or social media to use the app.

Are there any pure hookup apps?

Well, just like 3Fun, Feeld is a dating app to help you out. Feeld works much like Tinder; log on through Facebook (theres an option to change your name), choose the composition of your group (2+1, or 1+1+1) and swipe through hundreds of potential matches in your area.
