In addition to WeChat's core private and group messaging functions, users can also find new contacts by using the application's Drift Bottle function, where a user records a message and sends it out to see in a virtual bottle for a stranger to pick up and respond. Its Look Around function, similar to some mobile dating applications, allows users to browse the profiles of other users who are in close proximity. It also has a function called Moments that allows users to share photo albums publicly with groups of contacts, much like photo-sharing application Instagram.
