Slack's new mobile dark mode is available for beta users

Nobody loves staring at a bright white screen all day, which is why dark versions of popular apps are useful for people whose eyes need a break. Workplace communication tool Slack has finally joined the ranks of apps that offer a dark mode — but there's a catch.

Dark mode for iOS and Android Slack users is only available in beta for the present moment. If you're not already in the Slack beta, it's not hard to sign up -- but there's no telling when your tester availability will be approved.

To sign up for the beta, open the Slack app and tap the three vertical dots in the right hand corner of the screen. When your profile appears, navigate to the bottom of the sidebar and select "Settings."

Once in Settings, the "Join Beta" option is at the bottom of the page. Entering your name and the email associated with your Slack account will put you on the list to join the beta. After that, it's a waiting game for approval.

Once you are approved (or if you already are), turn dark mode on by again navigating to Settings and toggling the mode on that page. The new option should appear underneath Advanced, in the column beginning with Accessibility.

Screenshots on Twitter show what Slack's dark mode looks on iOS devices, and it's... well, it's looking real dark. Quite dark indeed.
