Facebook and Instagram users can soon receive alerts about how much time they're spending on the apps — and set time limits for themselves.

The two social media giants are rolling out time-tracker tools that show you how much time you spend on the apps each day and over the course of a week.

Facebook says the goal is to help users curb their addiction to social media platforms. 

Mental health experts say excessive screen time has been linked to depression and sleep deprivation. They say substituting real face-to-face interactions with mobile communications is unhealthy.

Long Islanders like Bryan Forrest, of Port Washington, say that makes sense.

"I think at first it was a useful tool to reconnect or whatever, but I don't think it brings people together necessarily," he says.

Others, like fellow Port Washington resident Brittany Rosen, say nothing is going to cut their screen time.

"If they were like, you're really on for five hours a day, I'd be like, 'OK,'" she says. "I don't care."
