Card Check

Card Check turns your phone into a price checker for trading cards. Point the camera at a card and it identifies itself automatically, then shows what it's really worth — the live market price for a raw copy, and what graded copies have actually sold for. FIVE GAMES, ONE SCANNER Works with Pokémon, Magic: The Gathering, Yu-Gi-Oh!, Disney Lorcana, and One Piece cards. No mode to pick — Card Check recognizes which game a card belongs to from the card itself. WHAT IT DOES • Auto-scan — hold a card in frame and Card Check reads it. No tapping, no typing. Or pick a photo from your library instead. • Raw market prices — current market value by condition (Near Mint, Lightly Played, Moderately Played), pulled live. All five games. • Graded sale prices — median PSA 10, 9 and 8 prices from recent eBay sales for Pokémon cards, shown with the number of sales behind each figure so you can tell a solid number from a thin one. • Price history — see where a card has been heading before you buy or sell. • Collection — add the cards you own, track quantities, and watch your collection's total value move with the market. • Scan history — every scan is saved, so you can pull a card back up with fresh prices any time. • Sold listings — jump straight to recent eBay sales for the exact card. BUILT FOR COLLECTORS No account. No sign-up. No ads. Your collection and scan history live on your device, not on a server — nothing is uploaded, and nothing is shared with anyone. HONEST ABOUT PRICES Prices come from public marketplace data and are estimates, not appraisals. Graded prices show what already-graded copies have sold for — they are not a prediction of what grade your card would receive if you submitted it.

Verdict
The clearest difference is in-app purchases: Card Check at none against Grade Sync Pro's 1. Card Check also leads on update cadence (every 9 days vs every 3 weeks). On price, ads, device support and iOS requirement there is nothing between them.
