Its only purpose is to provide two 3D dice, being easy and straightforward to use.
To throw the dice you only need to tap the screen.
Dice are tridimensional and easy to see. There are no useless added features and no clutter.
Only two dice, to use freely.
Through them, you can play any game, without needing two physical dice. Very useful for these occasions in which you'd want to have two dice but have forgotten to carry them.
Though the dice are visually attractive (tridimensional and attractive) the main target in the design of this application has been to provide functional and usable dice.
