Enjoy this app I built to help me play the popular Catan boardgame. It's features include:
A board generator - perfectly random layouts for tiles with or without tokens for a varied game every time.
A dice roller - an on screen dice roller when it's inconvenient to use real dice.
The introductory ruleset - hand the new player the introduction rule screen to help them quickly understand the aim and rules of the game.
The whole thing only takes 3mb of space so keep it around for when you need it.
