Stop paying to grade cards that will never hit a 10. Card Centering Pro measures your card's centering in seconds then tells you if it's worth the submission fee. Front and back, down to the decimal. WHY CENTERING DECIDES YOUR GRADE Centering is the most common reason a card misses Gem Mint. A card that's 70/30 on the back can cap your grade at an 8 — no matter how sharp the corners are. Graders measure it with digital precision. Now so can you, before you spend a cent. HOW IT WORKS 1. Snap or import a photo of your card 2. Edges are detected automatically — or drag the guides yourself 3. Get exact ratios: 55/45, 60/40, 52/48 4. See the best grade each company would give it 5. Submit the winners. Sell the rest raw. FEATURES - AUTO EDGE DETECTION Point your camera at the card. The borders are found for you. - MANUAL PRECISION MODE Vintage card? Thick border? Drag high-contrast guides to any anchor point and pinch to zoom for decimal-level accuracy. - FRONT AND BACK ANALYSIS Back centering sinks more submissions than collectors expect. Measure both sides and see your true ceiling. - GRADING STANDARDS LIBRARY Current centering thresholds for every major service, built in and kept up to date. Know which one gives your card the best shot before you pick a submission. - YOUR COLLECTION, SAVED Every card you measure is stored with its ratios and estimated grade. Build your submission list over weeks, not in one sitting. - WORKS OFFLINE At a card show with no signal? Everything runs on device. BUILT FOR EVERY CARD Pokémon · One Piece · Lorcana · Magic: The Gathering · Yu-Gi-Oh! Baseball · Basketball · Football · Hockey · Soccer · F1 Vintage, modern, holo, foil, full-art, borderless. WHO IT'S FOR COLLECTORS — Screen your box before you submit. One avoided submission pays for the app many times over. SELLERS — Publish exact centering numbers in your listings. Measured cards sell faster and close higher. BUYERS — Check the photos in a listing before you bid. Don't overpay for a card that's off-center. BREAKERS — Rip, measure, sort. Know what's worth slabbing before the box is even empty. Free to measure. Upgrade anytime for unlimited saved cards and full front-and-back analysis.
