Android: A few years ago, we featured a handy little Facebook client called Fast. Earlier this month, Fast got a big update with a new design. If you're sick of the regular client, this one's worth another look. As always, Fast's strength is in, well, it's speed. Everything works super quick. The new design features an embedded mobile site, so you can get the best of both battery-friendly worlds. It also has a section for embedding the mobile version of chat. Unfortunately, Facebook has been pushing people towards the Messenger app more and more, but for now at least, Fast can let you message people without having to install a separate app.
