Die Roller for RPGs v2 is an app to generate random die rolls for common die sizes used in tabletop or virtual Role Playing Games, and is compatible with games such as Dungeons & Dragons®, Daggerheart™, Pathfinder®, and others.
Rolling multiple dice, even of differing sizes, is a piece of cake. Select how many of each size you want to roll, and tap "Roll these dice" ! There is a dedicated button for rolling duality dice, which reports not only the result but also whether there was a crit, and whether the roll was with hope or fear. You can turn on the ability to shake the phone to roll the selected dice, and also turn off sounds within the app. In addition, there is a setting to enable you to be aware of crits when rolling a single die!
