About this app

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, letting you check if the card has a 10 centering grade before you even buy it.

✅ Editable History: Every card you upload is automatically saved. Go back and review, edit, or compare past measurements anytime.

✅ Pinch-to-Zoom: Zoom in on your card's edges to make pixel-perfect micro-adjustments before finalizing your measurements.

✅ 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.

✅ Multiple Card Games: Centering Check supports your favorite TCG - Pokemon, One Piece, MTG, Yu-Gi-Oh - and all sports cards.

✅ 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.

Ratings and reviews

Free weekly use limit at 10 otherwise it's very good to great.

I can't frame my card right. It keeps zooming in and locks it in the wrong area.

Smooth. Fast. Best detection software I've seen so far.
