This is a great companion app to Letter Jam. It helps speed up the setup (especially when you have some players who take forever to create a word), but there is one big drawback: each time you go to scan cards, you have to watch the ENTIRE tutorial, which is surprisingly long, before it allows you to scan. Unless I am missing something, this gets really annoying, and is the reason I am unable to give this app 5 stars. Otherwise this app is fantastic and works much better than I expected.
UPDATE: Thanks to the quick response from the developer, it is true that you must complete a game in the app to stop the tutorial. I have raised my rating to 5 stars. Thank you for clarifying.
