Tinder is a dating app that allows users to anonymously swipe through photos of nearby users. If two users both swipe right on each other's profiles, indicating a mutual attraction, they can chat within the app. Tinder has over 1 billion swipes per day, has been active in 196 countries since 2012, and has facilitated over 10 billion matches. While competition from other dating apps exists, Tinder remains popular due to its fun and anonymous swiping feature that can lead directly to dates or hookups.
