The very, very specific:
Feeld: Feeld specifically caters to ethically non-monogamous folks, regardless of sexual orientation. So if you’re someone who’s polyamorous and looking for another partner (or to date casually), Feeld is a great option. If you’re looking to join the 18% of men that have had a threesome, Feeld just might be for you. Whether you’re in a couple or flying solo, the app will help you match with other people looking for a party of three. The app also has a “hide” setting so you won’t match with your Facebook friends.
Scruff: If you’re a guy that’s into hairy dudes, say hello to Scuff. The app functions similar to Grindr, but some guys report liking it more because they find the men on Scruff kinder and less judgmental than the men on Grindr.
Sweatt: Fitness routines are very important, and you just might want to meet someone who also goes for runs at 5 a.m.
