Centering50: TCG & Sports Card Grading Tool Stop guessing and start grading with confidence. Whether you are a hardcore Pokémon TCG investor, a sports card flipper, or a casual collector, centering is the #1 reason cards fail to hit a Gem Mint 10. Centering50 is the professional-grade scanner designed to help you predict your grade before you spend a cent on submission fees. WHY CENTERING MATTERS In the modern hobby, the price gap between a PSA 9 and a PSA 10 can be thousands of dollars. Professional graders at PSA, BGS, SGC, CGC, and TAG use digital precision to measure border ratios. If your card is even 2% off, you lose the Gem Mint dream. Centering50 brings that same laboratory precision to your smartphone. PRECISION FEATURES FOR COLLECTORS: "Smart-Snap AI: Our algorithm helps you detect card borders for lightning-fast scanning of modern Pokémon, Magic: The Gathering (MTG), Lorcana, and One Piece cards. Save time with AI-assisted alignment, then fine-tune for 0.1% precision." Auto-Straighten Technology: Don't worry about perfect alignment. Scan at any angle and the app will instantly fix the tilt. The "Magenta Line" Manual Mode: For vintage cards or thick-bordered sports cards (Topps, Panini, Upper Deck), use our high-contrast measurement guides to set your own anchor points with 0.1% accuracy. Grading Standard Library: Instantly compare your results against the official 2026 standards: PSA: 55/45 Front (New 2025 Standard) BGS: 50/50 for Black Label eligibility SGC & CGC: Real-time centering thresholds Front & Back Analysis: Don't get rejected for a 90/10 back! Measure both sides independently to ensure your submission is truly "Perfect." 15x Precision Zoom: Perfectly align your guides on thin silver or gold borders with our enhanced magnification tool. SAVE MONEY ON SUBMISSION FEES Sending cards to be graded is expensive. Why pay for a "Near Mint 7" when you could have known the result at home? Use Centering50 to filter your collection and only send your strongest candidates. It’s the ultimate pre-grading utility for: Pokémon TCG (English & Japanese) Sports Cards (Basketball, Baseball, Football, Soccer) Disney Lorcana & One Piece TCG Yu-Gi-Oh! & Magic: The Gathering DESIGNED FOR THE 2026 HOBBYIST We know you’re scanning in different lighting. Our app features Dynamic Contrast Adjustment and Skew Correction, so even if your photo is slightly tilted, our math remains perfect. HOW TO USE: Place your card on a high-contrast, flat surface (no sleeves for best results). Take a photo directly from above. (with the green bubble in center) Align the Centering50 guides with the card edges and the internal art border. (Optionally: Unlock the image and move/resize/rotate) Get your LR (Left/Right) and TB (Top/Bottom) ratios instantly. JOIN THE 50/50 CLUB Centering50 isn't just a calculator; it’s your secret weapon in the grading game. Download now and take the guesswork out of your collection. Note: Centering50 provides a highly accurate estimate based on physical centering. Final grades are determined by professional grading companies based on additional factors like surface, corners, and edges. https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
