Facebook Touch is a version of the Facebook website that is optimized for touch-screen devices such as smartphones and tablets. It offers a simpler and more streamlined version of the full Facebook site, with larger buttons and a more touch-friendly interface.

Facebook Touch can be accessed by visiting the regular Facebook website on a touch-enabled device. The site will automatically detect the device and redirect you to the touch version of the site.

Facebook Touch offers the same basic features as the full version of Facebook, including the ability to view and post updates, view and comment on photos, view and send messages, and more. However, it may not have all the features of the full Facebook website, and some features may be limited or modified to work better on touch-screen devices.
