CastralDice Roller for Tabletop RPG

Castral is the fastest, cleanest dice roller for tabletop RPG players. Roll any standard polyhedral die with a single tap — d4, d6, d8, d10, d12, d20, and d100 — and see your result instantly. No accounts. No ads. Works completely offline.

Designed for players of Dungeons & Dragons, Pathfinder, and other tabletop RPGs who want a lightweight, distraction-free tool that stays out of the way.

WHAT MAKES CASTRAL DIFFERENT

• One-tap rolling. Tap any die to roll instantly — d4, d6, d8, d10, d12, d20, and d100 all supported.
• Natural 20 and critical fail highlights. d20 rolls are automatically flagged for natural 20s and critical fails.
• Roll history. Every roll is logged with relative timestamps so you never lose track.
• Clean, minimal design. Light and dark mode, built to stay out of the way during play.

PRICING

Castral is free, with no accounts, no ads, and no tracking, and it works completely offline. Castral Pro is a one-time purchase (no subscription) that unlocks dice expressions (3d6+2, 2d10-1, and more), unlimited roll history, and roll statistics per die type.
