Tinder is a big hit with Millennials.

Launched last fall, this mobile dating app is hitting it big with its predominantly Millennial users—clocking in with 20,000 daily downloads, more than 2 billion rated profiles, 20 million matches, and 65 percent of users logging in daily and 80 percent weekly. What primarily distinguishes Tinder is the way it enables snap judgments based on member photos, a process “designed to be familiar and emulate the way we interact in real life,” as the website puts it. Relying on Facebook integration, Tinder lets users scroll through photos of people within their set parameters who are most likely to prove a match, tapping a green heart if interested, a red X if not. Tinder then connects users when interest is mutual, eliminating fears of rejection and unwanted attention.

The app shoots away any pretense that it’s not all about looks for this cohort and speaks to our culture of impatience (and the resulting emphasis on images over words) and hyper-efficiency.
