Parents will be able to see how much time their children spend on Instagram and set time limits, while teens will get reminders to take a break.
It comes a day before Instagram chief Adam Mosseri is due to appear before US Senators investigating online safety.
Instagram has been under increasing pressure over teens’ use of the platform in recent months. Its internal research suggesting that teens blamed Instagram for increased anxiety was the first in a series of revelations in France Haugen’s leaked documents from inside Facebook.
The US Senate Committee is expected to quiz Mr Mosseri on Instagram’s internal information on child safety and its plans – as well as what the committee calls “potential legislative solutions”.
The timing of the announcement by Instagram was “interesting”, said social media consultant Matt Navarra.
“Instagram’s boss will want to have something new and meaningful to show US senators when they grill him… the new features will give worried parents more tools to help keep their children safe when using Instagram, but many will wonder why it has taken them so long to act.”
Mr Mosseri also unveiled a new system to bulk-manage Instagram accounts. Starting in January, a new system will let any user see all their posts, or all their likes and comments, in a chronological list – and select several at once to delete in bulk.
