User Reviews and Ratings
★★☆☆☆Can’t manually add cards.
This app was great, but they’ve recently made a HUGE mistake. You’re no longer allowed to add cards that you’ve acquired anywhere other than this platform. Meaning that you have to buy the card through alt to track it, or search for the card; but you can’t add it to your collection for ease of access.
As soon as my cards that are in my collection are sold off, I’ll likely delete this app.
When you could add your cards in, this app was great.
★★★★☆Fix new update
New update has an issue where you scan a card and the whole app freezes! Please fix asap!!!
Great app otherwise. Always use it and never fails!
