Bumble, the dating app from former Tinder co-founder Whitney Wolfe where women make the first move, has launched a new service that will allow users to find a friend as easily as they find romance. The new BFF mode works just like the existing dating UI -- save that potential love-interests are replaced with potential friends of the same sex as the user. If both parties swipe right, then they can initiate a conversation with each other. The system will differentiate conversations by color: green for your new bestie, yellow for your new hot date. Bumble has also confirmed to Engadget that "for Bumble BFF, women see women and men see men. We approach every new product feature with safety in mind and we did not want people gamifying the system."
