Apps for board games

[MasterDecoy]

With the announcement of the x com board game stating that it will require an app to play it got me thinking. What other good apps are there for board games that you use. I've downloaded a few but I can't say I actually bothered to use one in game.

The only other game that need an app at this moment I know is "Alchemists" from CGE. Nice game, was sold out on the Essen fair in just two days.
