Earlier this year at its f8 developer conference, Facebook announced the mobile Like button for apps. At first it was only available in preview for some iOS developers, but on Thursday, the company announced it’s now available to all iOS and Android developers.

“People using a mobile app can directly Like the app’s Facebook Page, or any Open Graph object within the app, and share on Facebook,” explains Facebook’s Todd Krabach. “The mobile Like Button works seamlessly with the Facebook account the person is logged into on their device, allowing people to Like any piece of content, while in your native app.”

Developers can add the button with just a simple line of code. As Facebook notes, there are plenty of different places in an app to display it. For example, you can show it after a user reaches a certain level of engagement or as soon as they log into the app.

“We recommend testing different locations to determine which leads to the best engagement,” says Krabach. “It is also important to select locations on the screen that resonate with your existing app experience and user interface. Some apps also show a pop-up dialog with the Like Button at the right moment in the app when people want to engage or share content.”

According to Facebook, the Like and Share buttons are viewed across 10 million websites daily.
