How we compared
We read each app's App Store listing, its in-app purchase list, its website and its Google Play listing if it has one. We did not test scan speed or accuracy, and we haven't quoted download or revenue estimates. Ratings are App Store US averages as of October 2026. Many of these apps list several prices without billing periods, so check the price in the app before you subscribe.

The apps in more detail
Binder AI
Binder AI is an AI pre-grading app for iOS, Android and the web. You photograph the front and back of a card and get an overall grade estimate on the PSA, BGS or TAG scale you choose, with centering, corners, edges and surface subgrades and written condition notes. It also has a manual centering tool, identifies the card, shows eBay sold prices, price history and a graded value table, and sorts cards into binders by game or sport with sharing and wishlists. It supports Pokémon, Magic: The Gathering, Yu-Gi-Oh!, One Piece, Digimon, Lorcana, baseball, basketball, football, hockey, soccer, WWE and non-sport cards. The app is free to download, and grading is included in a subscription: $1.99/week, $3.99/month or $24.99/year on the website ($4.99/month or $29.99/year in the App Store).
StarSnap
The most rated app in this group. It identifies sports cards from a scan or an uploaded photo, calls out autographs and limited editions, and comes in 12 languages. Premium adds unlimited identifications and market reports. Read Binder AI vs StarSnap.
Cardly AI
Sports cards first, with Pokémon, Magic, Yu-Gi-Oh!, Digimon, Lorcana and One Piece too. It adds an AI chat, price history, collection value and a batch scan purchase. Read Binder AI vs Cardly.
Cardstock
A collector's database as much as a scanner. It has set checklists with shared templates, nested folders, iCloud sync and CSV export, and its eBay sold values switch between raw and graded. Read Binder AI vs Cardstock.
Spoly
Prices from eBay sales, auction results and marketplaces, plus reminders for releases, grading submissions and listing deadlines, notes and tags, and a watchlist. Read Binder AI vs Spoly.
Digital Grading Co
A grading app that added sports scanning. It scores cards on its own DeepMint scale with five subgrades, including structure for warping, and a confidence score. It doesn't predict a PSA, BGS or CGC grade. Read Binder AI vs Digital Grading Co.
Sports Card Scanner Value
A simple app that identifies a card from a photo and gives its edition and an estimated market value. Its listing doesn't describe collection features. Read Binder AI vs Sports Card Scanner Value.
