The two drawbacks to Circle are that you have to have Facebook and an iPhone to use it, but otherwise, this roommate-finding app is one of the best ones out there. Circle functions like Tinder in the sense that users swipe through candidates to find their verified "match," but the mission of Circle is to connect users with people they trust — whether that's a friend of a friend or another verified user.
As one user explains: "Not only did Circle have a seamless interface and stress free sign up, but I immediately found matches through my mutual Facebook friends. After a week, I was dropping off a security deposit to my new roommate (a mutual friend of a friend) and moving in the next day. Highly recommended!"
