Tap to roll, no funny business.
Dieroller is a simple, elegantly designed die-rolling app without any silly extraneous features like shake-to-roll, pseudo-3D, or physics simulations. If you dont need switches, buttons, submenus, and other nonsense keeping you from checking against that Beholders AC, then Dieroller is for you.
You get the full basic set (d2, d4, d6, d8, d10, d12, d20, d100) all on one screen, with support for all device sizes, resolutions, and orientations.
