This app shows you two versions of the same Android App using ProductFlavor from Gradle plugin.
In the full version you can calculate which week of the year is and the app will tell you if it is correct or it is not however the demo version always tells you it is incorrect.
This feature is very usefull if you want to have a pro and demo version of your app in order to earn some money with your full (pro) version of your app with more functionality or less adverts than the demo one.
