Ratings and reviews

Overall, I find this app worthless. I got it because it's supposed to be able to scan My Hero Academia cards. I couldn't get it to identify a single card. I've used plenty of other TCG card scanning apps, and have never run into problems like this. Even attempting a manual search, the app kept hanging up. Downloading it was a waste of time and resources.

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!

App just does not work. When I open the app it just sits there and shows a spinning circle. I have to switch to another app and come back a few times before it loads the home screen. When I finally did get in the app I tried creating an account and it just shows a spinning circle next to create account. Tried on wifi and 5G and the results are the same. I uninstalled and will find another app to value my Korean pokemon cards
