Cool idea but needs LOTS of work. 1st of all, you get 2 free scans before you have to get the paid version. I chose 2 cards, 1 with obvious centering issues and 1 that looked just about perfect to my eyes. The centering is done manually, not with AI - you'd have to be a surgeon to let off the corner and not have it move while adjusting for each of the inner and outer corners. As a result, both cards were rated an 8 despite one of the cards obviously off centered.

We added the Zoom feature to make marking cards easier than in other apps. Both cards rated 8 follow official grading guidelines - an 8 fits within a defined centering range. Even if one looks slightly off, both qualify. By leaving a 1-star review, you're unfairly defaming our work.
