Grimoire is a character sheet manager that adapts to any tabletop RPG system, including one you invented yourself. Most sheet apps are built around one set of rules. This one lets you write the rules, so the sheet matches your table exactly instead of almost.
Android for now.
Features
Everything you make works without a connection, and the app keeps it on your phone.
Full character management with attributes, skills, derived stats, resources, inventory, and notes.
Roll any die from d2 to d100, including Fate dice. Supports icon-counting, exploding dice, advantage, and reroll mechanics.
Build any RPG system from scratch: define attributes, skills, formulas, resources, collections, dice rules, and advancement costs.
Derived stats auto-calculate with a safe expression evaluator. Toughness + Tier? Willpower + Armour? Just type it.
GMs curate catalogues of weapons, talents, and items. Players import them, and reimporting an updated pack rewrites the matching entries already on their sheets.
Organize games into campaigns with shared party resources, journals, bestiary, and initiative tracking.
How it works
Step 1
Build your own RPG system with our visual editor, or import one shared by your GM as a JSON file. Define attributes, skills, derived stats, resources, and inventory sections.
Step 2
Create a game, add campaigns, and fill them with characters. Each campaign has its own journal, bestiary, initiative tracker, and shared party resources.
Step 3
Fill in your character sheet, track XP advancement, manage inventory, and roll dice. Everything auto-saves to your phone: no account, no sign-in, nothing of yours passing through us.
Themes
Five handcrafted themes to match the mood of your campaign.
Crimson & gold. For dark, gritty campaigns.
Clean and sleek. A modern take on dark mode.
Warm and classic. Like a weathered spellbook.
Bright and minimal. Easy on the eyes.
Violet and candlelight. For magic that costs something.
Build your first game system, and never fight a sheet that almost fits again.
