KNOXVILLE NEWS SENTINEL - Oct 17 - Apps like Tinder, Happn and Bumble have been known to be used more for hookups. This influenced Hinge to rebrand as the "relationship app," which launched last week. Now for a fee of $7 members have access to users who are looking for more than just a hookup. Hinge refers to the new app as "Instagram profiles for dating." The app encourages conversation. When the user opens the app, they see the people with whom they have already matched, making the experience about the existing connection, not the next one.
