FB Pages Manager is a beautiful Windows Phone app that you can use to manage all your Facebook pages.
The app allows you to post, delete or share your pages status, upload photos, send and receive messages from your pages, comment on 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.
The app currently has more than 20,000 active users, and it is chosen by Microsoft as the best alternative to the official Facebook Pages Manager app.
The normal price of the app is $1.99 but currently the app is on sale for a limited time, so you can get it for $1.49 now.
There is a free lite version too.
There is an ongoing beta program for version 1.2, if you are interested in joining as a beta tester please send a message to the Facebook page of the app mentioned below. Being an active beta tester you will get the latest full version of the app for free.
Stay tuned on Facebook or Twitter for future updates. Version 1.2 will be released in September.
