Ratings and reviews

love the concept of this app and it's approach to TCG collecting. Unfortunately it's too buggy for me. I couldn't use the app to add cards, kept erroring out. Some selection boxes wouldn't scroll and needed text input for filters only. I also collect TAG and it's not yet supported. I'll try this app again after it's had some maturity on Android. Great idea, just needs polish!

seems like a awesome app but prices are still slightly behind tgc player and is missing alot of cards from op14

worst app out there. you cant remove cards from collection, scanner is 90% of the time inaccurate
