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!

doesnt seem to work. errors when trying to create an account and the scanner wont work. anything I try to upload fails or says it cant recognize it.

Loved the iOS version, but Im mostly an Android user, so Im glad it finally transferred over. Still in the works but the creator is very responsive and works to fix as much as he can on it.
