Some time ago, Facebook decided to separate Messenger from its official app, therefore, if you want to publish things on your timeline whilst you chat with your contacts, you need to download two separate applications. However, this tool here, Face Slim, integrates both functions in a Lite version of the social network's application.
An alternative to Facebook Lite
Therefore, this is basically a Lite version that integrates both the social network and the messaging app, preventing us from having to download both tools. And that's because it's the web version designed for mobile devices packed inside an APK.
In other words, this is a client for the most famous social network in the world that comes along with all the functions and features that we can enjoy on the web and that hardly takes up 1MB of space. However, if we're concerned about our privacy... well, if we were concerned we wouldn't be Facebook users to start off with. Apart from that, the developers of this FB Slim promise that they don't gather user information. If you believe them, just download this app as it's quite comfortable and works really well.
