AppCheck APK

Some fixes and notification added.

An application that provides valuable inputs to its consumers about their app usage behavior. AppCheck will read your app usage from the outside the app and provide accurate information like how many apps are installed in your mobile, how many apps were used by them in a day, for what duration were each of these apps used and other analysis. We will not be reading any information within the app as we know that it's personal and we don't have your credentials / approval.
