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.

The UI is easy to use, and well put together. The map components look amazing and feel like a real map not a cluster of busy renderings like other map making software. I like the connectivity, and being able to sync multiple devices. I like cross platform connectivity also. You can make your maps as simple as you like, or you can build a city and all the surrounding country side. The subscription price is easy to swallow and feels very reasonable. I love this app. Must have!!

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.

Thanks Simply Zee. We're sorry to hear the Calamus wasn't what you were looking for in a mobile mapping tool. If you have any suggestions for how we could improve, we'd love to hear them. You can shoot us a line at

The app is great but it freezes often making it hard to use. The ability to export a copy of the map as a image that could then be printed or attached to my notes would be super helpful. I would also like to see countertops for use in Taverns and shops. With this being such a new app it has a lot of potential for future greatness.

Thank you for your review! Let us know where the app is freezing on you and we'll try to get it straightened out. Email us at You can currently download your map for printing on the desktop build. This will be coming to mobile soon. Also, more tilesets will be coming soon!

What's new

Repair for two issues:
1. Tapping to place area tiles on a map could lead to incorrect tile placement.
2. Game owners unable to move player tokens.
