Ratings and reviews

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.

What to say, fantastic app! very different from other center tool, because of the Zoom which make everything easier! keep up the good work. Very accurate!

zoom in for corner is a help. going to see how well it doesn't against the card as it comes back
