Vol. I · A companion for in-person 5E play

Where the table
meets the realm.

A quiet companion for fifth-edition tabletop play. The maps you draw, the NPCs you scribble, the dice you roll — finally in one place.

Three at the table

For everyone the dice touch.

◐
For the Dungeon Master

The laptop at the head of the table. Campaign codex, NPC web, world map, encounters.

✦
For the Player

The phone in your pocket. Character sheet, spellbook, dice tray, live initiative.

◇
For the Table

Both, synced. The dice still hit the table. Snacks still get eaten. Story stays in the room.

CHAPTER I

For tables that
still meet in person.

Isometra is two views of the same world. The DM Command Center sits open on a laptop at the head of the table. The Player Companionsits in your players’ pockets. They sync. The dice still hit the table.

CHAPTER II

A codex for what you can't hold.

NPCs and the favors they owe. Locations and what hides in them. Quests, their threads, who pulled them. Treasure, its weight in plot. The campaign keeps a thousand small things; Isometra keeps them sorted.

CHAPTER III

A map that knows its own people.

The Cartographer pins every NPC, quest, trap, and session onto your world. Toggle the layers — see only hazards, only the path your party has walked, only the social web. Find the gaps.

CHAPTER IV

The party, in pocket.

When your wizard prepares spells in the morning, they reach for their phone. When the rogue checks for traps, they tap their dice tray. The DM's table and the player's pocket share one truth.

Questions, asked sideways.

01.
Do my players need accounts?
Yes — but only an email. They build their character on their phone before the first session, and join any campaign by link.
02.
Does this replace a virtual tabletop?
No, and it doesn't want to. Roll20 and Foundry are excellent at remote play. Isometra is for the table you're already sitting at.
03.
What about the rules?
The 5e SRD is wired in via Open5e — every spell, item, and monster. For non-SRD content, you can add your own.
04.
Can I bring my own world?
Yes. Start blank, sketch the realm, drop pins. Or fork a published world from /discover and customize from there.
05.
Have a character sheet somewhere else?
Imports from other character-sheet apps are coming soon. For now you can build by hand in a few minutes — we sweat the input UX hard.
06.
What rules editions are supported?
Today: SRD 5.1 and SRD 5.2.1, both included by default. New editions get added as the publishers release them under permissive licenses; homebrew rules can be added per-campaign without waiting on us.
HOW TO BEGIN

Three steps to the first roll.

I
Begin a campaign

Name the realm. Choose a setting (your own world, fork one from Discover, or start from a blank slate).

II
Invite the party

Send a join link. Each player builds a character on their phone.

III
Run the first session

You bring snacks and dice. Isometra brings the rest.
