(Pocket-lint) - The Google app is updating to offer a dark mode. Android and iOS users will notice the new option by the end of May.

Keep in mind Google has been rolling out dark modes across all its apps within the last year, including Gmail, Google Calendar, and Google Fit. And both iOS and Android began supporting dark mode at a system-level last year. Anyway, here's how to turn on the Google app's dark mode.

How to get dark mode for Google app

Install or update to the latest version of the Google mobile app. Once the new update arrives, the app will automatically use the default theme of your operating system. So, if your iPhone or Android is set to a system-wide dark mode, the Google app will appear dark. 

Google also said you can manually toggle between the new dark mode and old light mode under settings in the Google app. Just open the app, go to Menu in the corner, then select Settings, go to Choose Theme, and tap Dark. That's it. 

So, users with older phones or those running older operating systems will likely have to use the manual route. When the new dark mode is available for the Google app installed on your iOS or Android device, 9to5Google said you might see a pop-up notification on your screen.

When will the dark mode be available?

Google said the feature is starting to roll out from 18 May, but it won’t be globally available until late May.
