Taking into account the 2018 update - which changed the interface and how many users interact with app - we help demystify the most popular form of social media among young adults. Whether you’re a Snapchat veteran or a complete newbie, our guide will get you started and run through some of the app’s more integral features, including how to send and receive snaps and interact with the app’s Stories feature. When you receive a message on the app, commonly referred to as a snap, it will appear for only a few seconds (or a bit longer, depending on your settings), but once you click away or the time limit expires, it’s gone for good. Snapchat is a popular (or some might say, once popular) photo-messaging app that allows users to take photos, record videos, add drawings, and send them to their friends.
