If little Johnnie wants an iPhone app, he'll have to ask Mom first.

That's one aspect of "Family Sharing," a new iOS 8 feature unveiled by Apple on Monday at its Worldwide Developers Conference.

With the new feature, up to six people would be able to share music, books and apps -- as long as they're using the same credit card for iTunes. There's also a shared calendar and photo album.

So, if you're all Justin Bieber fans, you only have to buy his album once. The same goes for Minecraft.

For parents who want to keep tabs on their kids' purchases, there's the "Ask to buy" setting, which will send a prompt to a parent when child wants to purchase an app.

If tracking kids -- or their missing devices -- is a priority, Family Sharing uses Find My iPhone to show all that on a family map. As Apple put it on their website: "Finding your family's lost devices is even easier now that everyone can help."

Family Sharing earned a cheer from the crowd during the keynote speech at the developer conference. (Although, really, there's lots of cheering for all sorts of things during Apple keynotes.)

Moms With Apps, a network of developers who create kids apps was quick to release a statement from Sara Kloek, who runs the organization's best practices program called Know What's Inside.

"Family accounts will help developers innovate and create even more exciting apps," Kloek said. "We are excited to see where this new opportunity will take our developers and how it will affect the kid app space."

The new feature will roll out this fall with the rest of iOS 8.

The Verge has a rundown of "the 22 most important things Apple announced at WWDC 2014." Among them? An update to computer operating system, OS X Yosemite, and other new features for iOS, including a collaboration with the Mayo Clinic for the new HealthKit app.
