The Kickstarter for the Never-Ending Dungeon software has just launched. The tool reminds me of Dungeon Alchemist but supports also physical mapping:
https://www.kickstarter.com/projects/never-ending-dungeon/never-ending-dungeon/Never Ending Dungeon is a hybrid tool (printed maps and software) for creating adventures for both players and Game Masters. You can start the fun by using the adventures you find in the app, or you can create infinite number by your own.
