Google is expanding its suite of “Digital Wellbeing” tools for Android devices with a new feature, Focus Mode, launching today. This feature allows users to turn off distractions — like social media updates or email notifications — for a period of time, so you can get things done without interruption. Focus Mode was first announced at Google’s I/O developer conference this May, and has been in beta testing until now, Google says.

Unlike Do Not Disturb, which can mute sounds, stop vibrations and block visual disturbances, Focus Mode is only about silencing specific apps.
