Snapchat has updated its iPhone messaging app with a number of design and navigation improvements. Following the rollout of its "Banquo" update, Snapchat now offers the ability to double-tap messages to reply, has made it easier to add friends, and has rolled out new in-app profiles which mimic the public web profiles previously available in the app. The company has also introduced swipe navigation between the camera, friends list, and message inbox, while refreshing the camera screen with a more minimal design. Snapchat is yet to bring its improvements to Android, but iPhone users will enjoy being able to send self-destructing photos and messages a little speedier than before.
