Comments on Card Centering Calculator for Android

★★★★☆ Ysaak Benny · Sep 19, 2025
This is by far the best card centering calculator on Android, however, it has two glaring issues. Issue 1: No zoom feature, getting an accurate reading without zooming is quite difficult, luckily in the meantime, you can use the magnification accessibility feature to zoom. Issue 2: 5 cards per day limit, I'm okay with developers limiting features in free apps, however, 5 is a low limit for someone who regrades even a moderate amount of cards. Fix these issues, and I would be willing to pay.
★★★★☆ Jeremiah J. · Aug 5, 2025
Manually adjusting card is very difficult with touch screen, some up or down/left or right buttons to move it pixel by pixel would help. Also auto-detection does not work.
★★★★☆ Tony Snark · Jan 29, 2026
Pretty good! But the auto-detection gets it wrong every time, and the app DESPERATELY needs a zoom in function. A button to toggle the visibility of the markers would be great too! Adjustments are difficult when so zoomed out, and it's very difficult to see what you're doing when rotating with the markers in the way. Other than that, it tells you what you want to know once you get them in place. And it has a lot of helpful info about each grading services' standards.
★☆☆☆☆ Raphael Landry · Oct 15, 2025
Don't waste your money. Auto-detection doesn't work, every card's goes PSA 10 and if you want to go manually, It's impossible to set the borders because you cant zoom on your picture so you cant really have an accurate result. Bad application 👎
★☆☆☆☆ Lou E · Sep 6, 2025
Just doesn't work. I took a picture of multiple cards, and they all showed perfect centering even though the picture wasn't lined up with the outline. Maybe I'm just lucky & have the most perfectly centered cards, but I doubt it.
★☆☆☆☆ Pain Killer · Sep 19, 2025
Doesn't auto-detect card alignment, don't give even a present ir a visual, so you could center the card before taking the picture.
