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.

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

Great and gorgeous map making and I’m still learning even now. Things seem a bit hard to learn but I’m getting better and better with it.

Needs some fixes

I’m not trying to mean or anything. Just the truth. I found this app pretty much unusable for me. The text is incredibly small. The menu screen swipe function just doesn’t work well, so I was trapped on the first part I went to. But the biggest turn off for me for me was the rune password thing, I didn’t know what it wanted me to do so when I touched the screen trying to figure it out I picked some random tunes and have no clue what my passcode is now. I really think this could be something good, I will gladly give it another try and re-rate it if these things are worked out.

We're sorry you found the app unusable! We'd love to get your issues resolved as soon as possible. I'd like to start with the text being so small as to be unreadable. Would you mind sending a screenshot of what you're seeing to so we can ensure that you're seeing the app correctly? As for the menu screen swipe function, do you mean you're having an issue pulling out the right bar? We had that issue very early in beta testing, but increased the size of the hit area and haven't seen that since, but we'd be happy to explore that again. Finally, the runic lock. We will gladly reset your passcode if you email us your username. You can then change your passcode in options, and even disable it (though you will have to enter it again if you log out or go to another device). Also, your comment has prompted us to put a tutorial overlay on the runic lock, so expect to see that in the next build (which should come out soon!) Thank you so much for your feedback!

Beautiful, but...

I think there is a lot to love here. The graphics are quite nice. I haven’t tried to join a game yet, but...

My main perceived drawback is figuring out how to use the app in the first place. I’m in the free week trial, and I’m making my way through a very slow learning curve. Admittedly, I’m not very tech savvy, but is there a simple tutorial? Can maps be exported as pdf’s? Printed?

I feel like this app could be a DM’s dream come true if I could just learn how to use the features.

Developer Response ,

Thank you! A DM's dream is certainly what we've been trying to create. In fact, as DMs ourselves, the Calamus IS our dream, but we've a long way to go, so your feedback is very prized. It sounds like you're feeling a little overwhelmed by the features and tutorials from the get-go. If there's anything specific (or general) we can help with, please don't hesitate to reach out to us at
