I will try to explain again.
Skinery Tile is creating tiles which start other applications.
But these tiles are 'fake' and do not work properly as you would expect.
With the tiles created by SkineryTile app, you won't see the number of missed calls, or missed messages or any information which live tiles display.
This cripples the Windows Phone experience and creates confusion for users.
This is because the apps do not know about and cannot communicate with the tile created by the Skinery Tile.
Skinery Tile happens to be able to run certain applications which expose a special feature (can be started by invoking a URL).
Again, I do not wish to bash this application. I like the ingenuity of the creator.
But the application is useless and I wouldn't recommend it, it cripples the Windows Phone experience.
I am sorry but it shouldn't even passed the certification, because it creates confusion for users.
If the creator of this app loves Windows Phone he shouldn't promote this app
