Dark Mode inverts system colours, reducing strain on battery life and on your eyes. It also looks pretty cool. The customisation option has now been added to Slack’s mobile apps for Android and iPhone. Here’s how to turn it on.

  • Launch Slack
  • Tap the three dots icon at the top right
  • Choose Settings
  • Click Dark Mode
  • Slack may prompt you to restart the app (press Continue)

    The new feature has only just begun rolling out, so some Android users won’t see this option just yet.

    If you can’t see the Dark Mode setting (it should be below Advanced) ensure you are running the latest version of Slack:

    • Launch Google Play
    • Click the three lines at the top left to open the Options menu
    • Click My apps & games
    • Select the Updates tab and scroll down the list to see if a Slack update is available

    If no update is available and you want Dark Mode now, you can opt to install the beta version of Slack:

    • Head to
    • Click 'Sign up on Google Play'
    • Click 'Become a Tester'
    • Launch Google Play
    • Click the three lines at the top left to open the Options menu
    • Click My apps & games
    • Select the Updates tab and hit refresh next to ‘No updates available’

    The update may take a while to appear, but when it does you should install this to gain access to the Dark Mode setting.

    To revert to the standard version of Slack just uninstall the app and reinstall the public version via Google Play.

As the Maserati or BMW of laptops, it would fit perfectly in the hands of a professional needing firepower under the hood, sophistication and class on the surface, and gaming prowess (sports mode if you will) in between.
