If you manage multiple Facebook Pages like I do, you'll know that you can't really do much with your pages on your phone. Thankfully though, Facebook have at last released a dedicated Pages app so you can keep up to date with all your pages in one app, on your smartphone.
You can do all sorts which you couldn't before. You can now go through all the notifications for your pages, how many likes your posts/pictures have got, what comments have been left and one of the most important features, insights. You can really get down into analytics behind your page, it's not as in depth as on the full Facebook site but it should be sufficient for most.
