How does Bumble, the dating site, function?

Bumble is a location-based social and dating application that facilitates communication between interested users. In heterosexual matches, the app allows only female users to make the first contact with matched male users, while in same-sex matches, either person can send a message first. Users sign up using their phone number or Facebook profile, and they must provide pictures and a brief bio. Bumble uses a swipe right or swipe left feature similar to Tinder, where if two users both swipe right on each other's profiles, they are matched and given the opportunity to chat. The unique aspect of Bumble is its time-sensitive nature: after a match is made, there is a 24-hour window in which the woman can initiate conversation before the match expires. In same-sex matches or friendships (enabled in the BFF mode), either person has 24 hours to make the first move. The app also has features for finding friends and professional networking, offering multiple ways for users to connect beyond dating.
