You don't want to borrow your mate's sticky and misfortuned dices? Then use this app instead!

RPG-Dices II rolls d4, d6, d8, d10, d12, d20, d100 and counts up throws and results. You can also enable bonus dices and customise colours.

It is considered for all dice-based role-playing games (e.g. D&D and Earthdawn).
