Multi-pool rolls with drops, rerolls, and exploding dice, on iPhone, iPad, and Mac. Formerly Die Roller for RPGs 2.

Fritillon's Roll Dice screen with two shaped pools and their subtotals

Shape this pool sheet, showing settable options to name the pool, set its damage type, drop high and/or low dice, turn on mechanics like exploding or reroll, and adding another pool of the same die size

Shape every pool

Name each pool and give it a damage type. Then, per pool, drop the highest or lowest dice, reroll once, reroll until a die beats a number, or explode. Up to 50 dice in a pool, d4 through d100, all free.

See every die roll

Every die in every pool, not just the total. Rerolls and explosions are shown die by die, and roll history keeps every roll with its breakdown.

Roll results including a pool with a reroll mechanic enabled, showing individual die rolls broken down by pool, the result of the reroll, and the total

On every device

Sets, Groups, and roll history sync through iCloud across iPhone, iPad, and Mac, and the Mac version is a native Mac app. Copy any roll and paste it into your virtual tabletop, chat, or game notes.

The optional Dice Library

Everything above is free. The Dice Library is a one-time purchase, with no subscription, that lets you save your own Sets and Groups and edit saved Sets. Using and deleting Sets is always free, and so are the starter Sets the app comes with. One purchase covers iPhone, iPad, and Mac.

Fritillon comes from the Latin fritillus, a dice cup, the one on the icon. The same word named the fritillary flowers, likely for their checkered petals, and the fritillary butterflies, whose wings carry the same pattern.
