## What is Card Centering Check?

Card Centering Check measures how well the front of a trading card is centered. Pick a photo and the app finds the card's outer edges and artwork border, then shows the left/right and top/bottom border ratios with a reference grade.

AUTO DETECT
• Finds the card's outer edges and artwork border and places 8 guide lines for you.
• Straightens slightly tilted photos automatically.

FINE-TUNING
• Drag the handles to adjust any line; a magnifier follows your finger.
• Tap a handle and nudge the line 1 pixel at a time.
• Pinch to zoom up to 8×, and rotate the photo in 0.1° steps.

CLEAR RESULTS
• Live left/right and top/bottom ratios and a reference grade.
• A "borderline" hint when a ratio is just past a grade boundary.

RECORDS
• Save a measurement with a note, such as the card name.
• Sort by date or grade to pick the cards worth submitting.

RESULT IMAGE
• Create an image with the guide lines, ratios and grade, then save it to Photos or share it.

PRIVATE BY DESIGN
• Works fully offline. No sign-up, no tracking.
• Your photos are processed only on your device and are never uploaded or saved.

The reference grade is calculated from published centering standards and is for reference only; it is not an actual grade. This app is not affiliated with any card grading company.
