So one that I noticed was:
Taking Notes and Outside Material Players cannot take notes or reference outside material or information during a tournament round. However, players may reference official rule documents or game components that do not contain hidden information at any time or ask a judge for clarification from official rule documents. Official rule documents include all rules documents available on the Star Wars: Armada page of our website, those found in a Star Wars: Armada product, or any portion thereof.
I commonly used my Builder app to check cards without disturbing my opponent. I guess that is a No No now as its not an official FFG product.
FFG stop messing around and build a Squadron Builder please.
