About this game

The Calamus is a companion for tabletop roleplaying games, such as Dungeons & Dragons or Pathfinder, that allows you to create huge battlemaps utilizing dozens of hand-drawn tiles, create custom PC, NPC, and FOE tokens, and host games in which players can add and move their own characters in real-time.

The Calamus also features a robust chat, in which you can send messages as yourself or any token you have in play, publicly or privately.

Fog of War and 2x2 Characters have recently been added.

Desync is terrible, and as of now, I've lost access to the premium subscription content that I pay for. I thought my subscription ran out, tried to refresh it, but Google Play tells me I already have a subscription. I cancel the preexisting one, start up a new one, only to STILL not have premium. On top of that, your password system is buggier than a roach infestation, and I can no longer sign in. Reset my password multiple times, new password never works.

The UI is terrible, the tools are a pain to find and use, I couldn't even tell what this app was for until I got an email asking me to subscribe (classic scenario where I downloaded it along with a few other apps of it's sort, and forgot a few days later.) Don't waste your time, if you're okay with paying for a mapping tool, get Illwinter's Floorplan Generator on steam. Best mapping software I've tried. For free maps that are roll20 compatible, go to the maps are basic but good.
