DiceCalc is a TTRPG dice managmeent system for players and GMs. Here's what it does: Roll all of a character's dice simultaneously — see every attack, save, skill, and modifier roll all at once via the Roll All mode with character tabs. Still reroll per macro — long-press any single roll to edit or reroll just that macro without rerolling the rest, even in Roll All mode. In-depth macro inspection — Roll Macro mode focuses on macro options, allowing players to inspect rolls, rename, edit, and sort the macro list. Sort order here is also preserved in Roll All mode. Cryptographically secure random number generation — higher unpredictability, more randomer. Sortable character tabs with up to 100 macros each — whether you're running or playing a campaign, organize by character, encounter, monster, game system, or any other way you like. Every major TTRPG dice mechanic in one app — keep high/low, target numbers (successes), botches, exploding dice, crit detection, multi-roll comma separation for staged (verification) rolls, and yes... push dice! Constraint validation with red-highlighted error feedback — pathological expressions are caught before they run, no infinite loops or broken math. Persistent 300-roll history with timestamps — every roll logged with full roll breakdown and no truncation. Tap-and-hold context menus throughout — edit, duplicate, delete, rename, reroll wherever it makes sense. Localized in 7 languages — English, Spanish, Portuguese, German, French, Italian, Polish, with complete in-app manuals for each. 14-page in-app user manual — every feature documented with examples, no need to leave the app. Supports Android 8.0 and above — runs on devices going back a decade. Custom QWERTY keyboard for macro names — with locale-specific diacritics via long-press. Independent horizontal scroll per output row — nerd out inspecting long expressions, results, and roll details without truncation. Also... I'm giving it away for free till 09/31/2026 11:59:59 (JST).
