Vina lets you swipe right to make new friends or join communities of people who have similar interests. You can also take quizzes and read articles. Founders Olivia June and Jen Aprahamian created the app to help empower women, who like to travel, have just moved to new cities, and so on. Set up a profile with photos and a blurb, and then browse other users' profiles. Swipe left if you want to pass, or right if you want to connect.
