Who should use it: Women who want control over their online dating destinies. Bumble was founded by Tinder co-founder Whitney Wolfe and has a very similar look and feel. Inspired by the Sadie Hawkins dance, women must initiate all conversations once a match is made. The opportunity to connect disappears after 24 hours. It's available on iOS in the U.S. and U.K. but will roll out on Android and other countries this year.
