HOW SURE ARE WE
Not in any grossing chart, so this comes from ratings growth (13 new ratings a month on average since launch): revenue grows with new ratings, more slowly for apps that collect ratings fast. Tested on 418 apps with verified revenue: typically off by about 2 times, and big earners tend to come out low. Countries we don't track (and Google Play in China, which doesn't exist) aren't included, and neither are ads or web payments. Gross revenue before store fees.

Not accurate

I checked my card and it said PSA 10. I sent my card to PSA and got 8! Not even close! Just wasted money on grading. (Edit!$ Developer responded to me but I guess they can’t read English… The app said centering was 10! But PSA result said “Centering was way off!” Yes the final number wasn’t about centering only. I’ve got 8 because centering was off and I’ve got a little scratch! But was included centering too! I hope that helps!

Store description

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.
