Facebook Dating is a Tinder alternative that does not come with left/right swiping but relies on shared Facebook connections instead. This service uses the data in one's Facebook profile, friends, Group memberships, and so on. The browser version is not available yet, and the mobile apps only work in Columbia for now.
