So far the app seems to be better than the collector app as more bugs a pair I’ll be contacting the creator to try to fix them out so this could be a superior app in the future… when I use the word better, I mean more detailed more information more insight…. Good job so far.
Fantastic!

This app has the potential to become the absolute best app for tracking collections. I’ve noticed some issues finding some items (seems they aren’t on here yet) and some pricing issues (some cards are marked way higher or lower in the app than the eBay link prices), but I’m giving benefit of the doubt since it’s new and in the works. Love the layout and all the options for tracking! So much fun to use!
I see the vision!

Giving it a 5 because I see the vision - first app of its kind, Keep at it I will keep on using it. I understand that the app is still getting better everyday, I’ve noticed that it is quite slow especially when adding collection manually (guardian did not accept collectors url to quick add). Can’t wait till it’s working at 100%!
Horrible

Honestly I have never struggle so much to scan a card it doesn’t scan when it does scan it freezes on the wrong card on top of that shows a bit of information then takes it off to scan again and freezes again i am kinda upset I paid the membership before trying the app our a littleBut that’s on me all other review show some bug but I can even use the app the add my cards with scan at all
Live scanning keeps up as you move between cards — the match sheet updates smoothly instead of staying stuck on the first result.
Tapping other potential matches now locks in your choice during continuous scan. Collection saves go to the correct card and portfolio.
Thank you for using Guardian TCG.
