Description by Gabin Williams Written by the developer, not by AppBrain. Click to read.
Stop guessing whether your card will hit a PSA 10. Start knowing — and know exactly what it's worth.

CenterGrade is the only app that combines AI-powered centering analysis with real-time market intelligence. Measure centering, predict grades for 6 grading companies, check live card values, and calculate your return on investment — all before you spend a dime on grading fees.

No subscription. No daily scan limits. No data leaving your phone.

MARKET INTELLIGENCE — KNOW BEFORE YOU GRADE

This changes everything. Search any trading card and instantly see real-time estimated values, interactive price history graphs, and Market Pulse liquidity scores. Market Pulse tells you whether a card is actually selling — not just listed. Investors and collectors finally have the data they need to make smart decisions.

ROI CALCULATOR — MAXIMIZE EVERY SUBMISSION

CenterGrade calculates your projected return for every grading company based on your predicted centering grades and current market prices. See exactly which grader gives you the highest profit margin. Stop submitting cards to the wrong company.

HOW CENTERING ANALYSIS WORKS

Point your camera at any trading card — or screenshot one from eBay, an auction listing, or anywhere. AI detects the outer card edge and inner border automatically, calculates left/right and top/bottom centering ratios, and delivers instant grade predictions. Takes about 5 seconds.

Most centering apps fall apart on dark borders, holographic surfaces, and vintage stock. CenterGrade was built for exactly these cases. Cards on wood, granite, fabric, and other textured surfaces are detected reliably. A built-in leveling guide and auto-capture eliminate angle errors.

SIX GRADING COMPANIES. ONE SCAN.

See predictions for PSA, BGS, CGC, SGC, ACE, and TAG all at once. PSA and BGS predictions are always free. CGC, SGC, ACE, and TAG unlock with Pro.

FRONT AND BACK — THE WAY PSA GRADES

Scan the front, flip the card, scan the back. Both measurements factor into your predictions. Stop losing Gem Mints to a back centering problem you didn't know about.

PRECISION TOOLS

Center any card no matter how bad the photo. Drag pins to fine-tune borders. Pinch to zoom up to 15x. Screenshot card photos on ebay and center them before you invest. Undo and redo up to 20 steps. Ratios update live.
