This icon has a transparent background which is shown as black borders in iOS when saving to the Home screen.

Furthermore, it would be a nice touch, if this could be modified with a personal icon. Or at least give the option to have a full screen logo without transparency. The app also allows for setting other types of icons - though not custom.
