After updating its desktop app with a major design overhaul earlier this year, Slack has released updated versions of its iOS and Android apps that aim to provide users with a simpler and more organized mobile experience. One of the biggest changes in the new mobile business redesign is the addition of tabs to provide quick access to everything users need at the bottom of the app. Slack's previous navigation system was confusing and unconventional, so it decided to go back to basics to provide a navigation experience that most mobile users expect in the form of a tab bar. New apps now include swipe gestures that allow users to easily navigate between screens. From any Slack tab, users can swipe right to open a list of their workspaces, or left to return to their last conversation. From within a conversation, users can also swipe right to return to their last tab. Slack also made it easy to work with other apps using shortcuts. Some apps include shortcuts that allow users to take action on another service without leaving the workplace chat app. This makes it easy to take action in Slack, like starting a call, setting a reminder, or creating a poll. To start using the app shortcuts, users just need to press the lightning bolt icon below the input bar.
