CenterMint - Card Centering

Know a card's centering in seconds — before you spend a cent on grading. CenterMint scans or imports a photo, auto-detects the outer and inner borders, and calculates exact left/right and top/bottom ratios right on your device. See PSA, BGS, and CGC odds, fine-tune every edge by hand, and share a clean branded score card — no account, no uploads.

Why collectors use CenterMint: • Instant centering — point at a card, lock the borders, and read the result the moment it snaps. • Real measurements — precise horizontal and vertical ratios plus your worst axis, calculated locally. • Grade-ready odds — quick PSA, BGS, and CGC centering estimates for front and back before you submit. • Sub-pixel editor — a magnifier loupe with undo and redo lets you nail every border by hand. • Your style — swap guide-line colors and styles in a tap, then export images that look great. • Free share cards — turn any check into a branded score card to post and compare. • Local history — save reusable checks and reference images, all kept on device.

Built for Pokémon TCG, sports cards, MTG, One Piece, Lorcana, Yu-Gi-Oh!, and any collectible where centering decides the grade.
