Free · In‑App Purchases

Centering Check is your premium pocket-sized tool for measuring card centering with pixel-perfect precision and getting instant grade estimates. Simply snap a photo or upload a screenshot of an online listing. Instead of worrying about perfect camera angles, our custom AI Warp Method instantly transforms your image into a flat, bird's-eye view, fixing any perspective distortion automatically. You have complete control to ensure absolute accuracy by manually adjusting the borders, giving you a precise look at the card's true centering in seconds. Key Features: ◆ Evaluate Online Listings Instantly: Take a screenshot of any online listing and upload it directly. Our AI Warp Method removes the angle distortion and auto-detects all borders, letting you check if the card has a 10 centering subgrade before you even buy it. ◆ Batch Ranking: Select multiple photos or shoot cards one after another. Every card is measured, saved to your collection log, and ranked by centering in a single pass, so you find the grading candidates immediately. ◆ Pinch-to-Zoom: Zoom in on your card's edges to make pixel-perfect micro-adjustments before finalizing your measurements. ◆ Editable History: Every card you upload is automatically saved. Go back and review, edit, or compare past measurements anytime. ◆ Accurate Grade Estimates: Instantly see estimated centering grades tailored to the specific front and back thresholds of major grading companies: PSA, BGS, CGC and TAG. ◆ Front & Back Support: Easily toggle between front and back calculations to get a complete picture of your card's centering quality. ◆ Share Your Pulls: Generate a sleek, shareable image of your card with its centering measurements and grade estimates overlaid - perfect for sharing with buyers, sellers, or your community. ◆ Grading Standards Reference: A dedicated section with the official centering thresholds for every supported grading company, so you know exactly what each grade requires. ◆ Zero Interruptions: Focus entirely on your card's centering without annoying pop-ups or banners. Stop wondering if your card is worth sending in for grading. Use Centering Check to evaluate your collection, prep your submissions, and buy or sell with confidence.
