Find my friends, an app native to iPhones, highlights the importance of social proof and liking. Users follow their friends on the app to see where they are at all times. The app lets you get directions to your friends’ locations, and you’re able to notify your friends if you’re nearby. Find my friends has become a symbol of close friendship in many circles. For example, my roommates and I all have each others’ locations. In deciding where to go out on a weekend, people may use find my friends to see where their friends are. The app by design only shows people you like enough to follow their location, and it becomes more useful as new people share their locations too.
