Most messaging apps have become all-in-one solutions, offering video calls, image sharing and even gaming, with the notable exception of Snapchat. Now the ephemeral messaging platform is widening its functionality, adding text chat with the ability to have a FaceTime-like video call if both users are online. These, of course, will be destroyed upon leaving the chat unless you use a save for later functionality on select messages. The addition of these features will likely boost engagement but will Snapchat lose some differentiation? Video calls are not saved by default on most services and text typically does not carry the same privacy concerns as images.
