Facebook is shedding some dead weight.

The social network on Monday announced it is shutting down tbh, a teen messaging and polling app it acquired last year, and two others due to "low usage." The other Facebook apps getting the boot are Hello and Moves.

Launched in 2015, Hello, which earned a "good" rating in PCMag's review, connects Facebook with your phone to tell you who's calling—even if you don't have their number saved. Facebook said it will be depreciating Hello "in a few weeks."

The fitness-tracking Moves app, which Facebook purchased in 2014, records your daily activities, including walking, cycling, and running. Facebook plans to depreciate the Moves app and Moves API on July 30.

Within 90 days, the company plans to delete all user data from all three apps.

"We regularly review our apps to assess which ones people value most," the company wrote in its announcement. "Sometimes this means closing an app and its accompanying APIs. We know some people are still using these apps and will be disappointed — and we'd like to take this opportunity to thank them for their support. But we need to prioritize our work so we don't spread ourselves too thin. And it's only by trial and error that we'll create great social experiences for people."

Meanwhile, Facebook also recently cancelled Aquila, a drone project it had been working on since 2014 that aimed to bring internet access to the estimated 4 billion people living in areas of the world where the infrastructure isn't in place to offer it.
