Google may announce a new set of Android controls tomorrow at its annual developer conference that will help individuals and families manage how much time they’re spending on mobile devices, The Washington Post reports.

It won’t be the first time Google has created controls for monitoring phone use. Google already offers a set of family control tools called Family Link which let parents restrict their children’s app usage time and remotely lock devices.

Other announcements the Post said to expect at Google’s I/O conference tomorrow include an update to the Google Assistant that will make it more interactive, and new tools for publishers to help pull up reliable search results. The report is vague on details.

Google’s CEO Sundar Pichai may talk about the theme of responsibility in his keynote, the Post said, and that may be reflective of the tech industry’s ongoing challenges with personal data protection. Last year’s keynote was focused on AI. Google will still emphasize AI to some extent, given what goes into developing the Assistant and search algorithms.
