The redesign takes an app that has long been limited to three screens and splits them into five. Snapchat currently opens to the camera, with a space for chats to the left and the Discover page — which features a collection of ephemeral stories from friends, creators, third-party publishers, and Snap itself — to the right. Perhaps most dramatically for Snap, which once seemed to pride itself in its obscure design choices, Snapchat is getting a navigation bar. You’ll be able to see where you are within the app at a glance, and move directly from screen to screen with a single tap instead of swiping.
