How to turn on Dark Mode in Slack

Slack now supports a Dark Mode on iOS and Android. Here’s how to enable it.

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.

This small mobile printer is exactly what I need for invoicing and other jobs such as sending fellow tradesman details or step-by-step instructions that I can easily print off from my phone or the Web.

Microsoft Office 365/Dell XPS 15 2-in-1

I’d recommend a Dell XPS 15 2-in-1 and the new Windows 10 to anyone who needs to get serious work done (before you kick back on your couch with your favourite Netflix show.)

Brother PT-P750W

It’s useful for office tasks as well as pragmatic labelling of equipment and storage – just don’t get too excited and label everything in sight!

The Brother MFC-L8900CDW is an absolute stand out. I struggle to fault it.

I need power and lots of it. As a Front End Web developer anything less just won’t cut it which is why the MSI GT75 is an outstanding laptop for me. It’s a sleek and futuristic looking, high quality, beast that has a touch of sci-fi flare about it.
