All page owners can manage their Facebook pages from their Facebook mobile app or Facebook Lite app. There is no actual need to stress yourself, but there is an app that has been made for managing Facebook pages.
Of course, like I said earlier, you can also manage your facebook page right from your Android device with your normal facebook mobile app. If you are now seeking to get more insights, more settings and more notifications from your page, I guess you should try Facebook Pages Manager.
