App is great, I love that you can access all rules and cards in the game and adding the soundtrack was a masterstroke. The save game option is kind of worthless unless the option of tracking each players deck and relics is added. Writing down that information as a "note" can take forever with just two players after act 1. I hope that's added in the future, but even if it isn't, this is a really helpful app.

Thank you for the feedback. This was a much requested feature. As of today a new save deck feature is available! Happy slaying!

When it comes to cool features, this app has lots of things to check out, like the soundtracks, the progress tracking or the rulebook to name a few. What I do wish we had was a more solid way of saving our progress however. I do appreciate that you made this app and that it's free, but I really feel like the app would be way better if the deck saving feature would show a little album to pick cards from, like in TCGs. I currently just take pictures of the decks to save. Thanks for your work!!

Great companion app but achievements don't work! I appreciate having a compendium, all the tools, rules, etc. but the main reason I wanted this app was so I didn't have to write in my rulebook. When I open the achievements section, boxes are shown but no text is showing after them. Hopefully this will be fixed soon so I can keep track of what I've done.
