"We're not building a phone, and we're not building an operating system," said Facebook CEO Mark Zuckerberg. Instead, the company is launching "a family of apps" for the Android smartphone operating system.
The new Home displays images from friends on the lock screen of an Android phone so that as soon as you turn it on, you see photos and text from your friends. It takes up the whole screen of the phone. To get to your other apps, you have to swipe it out of the way.
HTC and AT&T announced a new phone optimized for the Home app.
Facebook stock was up almost 4 percent for the day at 11:30 a.m.

MENLO PARK, Calif. (AP) — With its new "Home" on Android gadgets, Facebook aims to put its social network at the center of people's mobile experiences.Facebook has introduced software called Home that makes the social network the hub of any smartphone running Google's Android operating system. The idea behind the software is to bring Facebook content right to the home screen, rather than requiring users to check apps. "Home" comes amid rapid growth in the number of people who access Facebook from phones and tablet computers.
Available for download starting April 12, the service is part of Facebook's move to shift its users' focus from "apps and tasks" to people, said CEO Mark Zuckerberg during Home's unveiling at the company's Menlo Park headquarters on Thursday.
The new product, which can reside on the home screen of Android phones, is a family of apps designed around people's Facebook connections. Rather than see a set of apps for email, maps and other services on the screen, users will be greeted with photos and updates from their Facebook feeds.
"We think this is the best version of Facebook there is," Zuckerberg said.
Zuckerberg says users can have an experience on Android phones that they can't have on other platforms. That's because Google makes the software available on an open-source basis, allowing others to adapt it to their needs.
The move coincides with rapid growth among the number of users who access the social network from smartphones and tablet computers, and Facebook's aim to evolve from its Web-based roots into a "mobile-first" company.
"What Facebook wants is to put itself at the front of the Android user experience for as many Facebook users as possible and make Facebook more elemental to their customers' experience," said Forrester analyst Charles Golvin.
In addition to Home, a new HTC phone that integrates the service will also be available starting April 12, with AT&T Inc. as the carrier.
The move could help to attract more mobile advertisers. Though mobile ads were a big concern for Facebook's investors even before the company's initial public offering last May, some of the worry has subsided as the company muscles its way into the market.
Last year, Facebook began showing ads to its mobile audience by shoehorning corporate-sponsored content into users' news feeds, which also include updates from friends and brands they follow. Facebook now faces the challenge of showing people mobile ads without annoying or alienating them.
The mobile advertising market is growing quickly, thanks in large part to Facebook and Twitter, which also entered the space in 2012. Research firm eMarketer expects U.S. mobile ad spending to grow 77 percent this year to $7.29 billion, from $4.11 billion last year.
EMarketer said Wednesday that it expects Facebook Inc. to reap $965 million in U.S. mobile ad revenue in 2013. That's about 2.5 times the $391 million in 2012, the first year that Facebook started showing mobile ads. Clark Fredricksen, vice president at eMarketer, says "there are some clear reasons why a deeper integration with mobile operating systems and handsets make sense for Facebook. At the end of the day, the more deeply Facebook can engage consumers, no matter what device or operating system or handset," the better.
Earlier, experts predicted that the social media titan would dive into hardware with its very own smartphone running the Android operating system.
