About Grade & Scan cards : Gradeon
Before you pay to have a card graded, one question settles it: will the centering hold up?
Gradeon measures it. Photograph a card: the app identifies it, computes the centering to the percent, front and back, and compares it against the tolerances published by PSA, BGS, CGC and PCA. You know before you pay.
MEASURE THE CENTERING
• Automatic edge detection, sub-pixel precision
• Left/right and top/bottom ratios, front and back judged separately
• Estimated tier at PSA, BGS, CGC and PCA — with its margin of error, not a false certainty
• Magnifier and finger-precise nudging when you would rather place the lines yourself
SCAN ON YOUR IPHONE
• Recognition runs on the device: no external AI service receives your photo
• Name, number, set and language read straight off the card
• Burst mode: keep feeding cards without leaving the viewfinder
• When the app is unsure it says so and offers the candidates — instead of guessing silently
TRACK YOUR COLLECTION
• One row per copy: condition, language, finish, 1st edition, grading label
• Market prices in euros for Pokémon and One Piece, with history and portfolio value
• Set completion (12 / 207), your own lists, favourites and wish lists
• The Pokémon set catalogue ships inside the app: your sets open in airplane mode
TRADE WITHOUT GETTING BURNED
• The Matcher pairs your duplicates with what your partner is looking for
• Balance a trade to the euro; lock the cards you will never give away
• Double confirmation: nothing moves until both people have agreed
• Invite by QR code
GAMES COVERED
Pokémon, One Piece, Yu-Gi-Oh!, Naruto Mythos and Panini WC 2026.
