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)

  • Click the three lines at the top left to open the Options menu
