Pages Manager for Facebook is a universal Windows app which helps you to manage all your Facebook pages. But this is not an official app. But I found this app as a very useful one. The app allows you to update/delete/share your pages status, update photos, check and respond to your messages, comment to your posts or reply to a comment. You can view all your page insights, like or unlike, basically you can do pretty much everything on your pages that you do on your PC browser. Buy full version for more features.
Download the app and comment your views about the app
