## About

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.

Made by a small indie team. Email obeliskclubclub@gmail.com with feedback, bug reports, or feature requests.
