Permissions are sometimes difficult when you get apps or update them from Android Market or another places.
You can learn Permissions in this app by playing Quiz game or see the permission list.
In Quiz game, you can see the description of the permission, and then you should choose the right name.
The descriptions of permissions in this app are included in the System and I'm afraid that you sometimes will think them difficult.
But I hope this app is the chance that you learn the permissions to have more safe and fun experience of Android.
This app requires "full Internet access" for the online ranking and ads.
