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.

Deck turns your camera into a card scanner. Point it at any Pokémon, Magic: The Gathering, Yu-Gi-Oh, or sports card and Deck instantly reads the name, set, and number, identifies the exact card, and adds it to your collection with an estimated value — all on your device, even offline. Batch-scan a whole binder page in seconds. Watch your portfolio value over time on a clean dashboard with per-game and per-set breakdowns. Track master-set completion ("12 cards left to finish Base Set") with an automatic want-list.
