A companion for your tabletop campaigns — player and GM, sharing the table live.
One app, three views. Players use a live character sheet, Game Masters run combat and campaigns, and GMs who want to build their own material get a full authoring studio — all in sync, at the table, live.
One app, built for everyone at the table
Every table has different jobs. CritNexus gives each one its own surface, kept in sync.
Player
A character sheet that does the math — abilities, AC, saves, spells, and inventory — always in sync with the table you're seated at.
Game Master
A live dashboard and combat tracker, the full shared content library, and every player's sheet visible in real time.
GM+
Everything in Game Master, plus a full authoring studio — custom monsters, items, and a worldbuilding codex to share at your table.
The Beta test is available now
Current features that are live in the Beta.
Rules-accurate math

True-random dice with full breakdowns, tap-to-roll on saves, skills, strikes, and spells.
A real turn economy
Three actions and a reaction each turn, with penalties applied automatically on repeated strikes.
Conditions & resources
Hero points, spell slots, and custom trackers — all tracked live and applied to the math.
Inventory & wealth
Coins, gear, and encumbrance calculated automatically from what you're carrying.
GM dashboard & tracker
Run encounters across a table in real time, with every sheet visible.
A shared content library
Ancestries, classes, feats, spells, weapons, and gear — every entry clickable for full rules text.
