## What is Ding Detect?

DingDetect – Card Centering Checker

Know your centering before you submit. DingDetect lets you measure the centering of your trading cards in seconds and instantly see how your card stacks up against PSA, BGS, CGC, ACE, and TAG grading standards — right from your phone.

Whether you're deciding which cards are worth submitting or building a collection strategy, DingDetect gives you the data you need before spending on grading fees.

HOW IT WORKS
Take a photo or upload from your gallery, align the guide lines to your card's borders, and DingDetect calculates the top, bottom, left, and right centering percentages. Results are mapped instantly against published grading standards so you can see your estimated grade tier for each company at a glance. 

FEATURES
• Centering analysis for front and back of any card
• Grade predictions for PSA, BGS, CGC, ACE, and TAG
• Draggable guide tabs or edge sliders — choose the control style that works for you
• Scan history to track and revisit every card you've checked
• Dashboard stats showing total scans and per-company centering performance over time
• Customizable settings — show only the grading companies you care about
• Export and share your centering results as an image
