CenterMint: Card Centering

PSA grade odds before you pay

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

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. Privacy-first: Your card photos, measurements, and history stay on your device. CenterMint does not upload your images or require an account. Advertising and consent SDKs may collect limited data as described in the privacy policy. CenterMint is a collector utility, not a grading company. It estimates centering only, does not guarantee any third-party grade, and is not affiliated with PSA, BGS, CGC, Pokémon, Wizards of the Coast, Bandai, Konami, Disney, or any card brand. ——— Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://zhao73.github.io/centermint/privacy.html

  • This app hasn’t received enough ratings or reviews to display an overview.

• Full-art cards now report a clean automatic result when the inner frame locks onto the printed line — no more being asked to confirm every single scan. • The plan picker only ever shows plans you can actually buy, and every price now comes straight from the App Store. • Share images carry a QR code and a real link, so anyone you send a card to can find the app. • Fixed close and options buttons being invisible in Dark Mode inside the editor. • Pro exports are now genuinely watermark-free, as promised. • Terms of Use and Privacy Policy are now linked from the purchase screen.
