The best card grading app depends on what you want before or after a submission. Some apps estimate a grade from your own photos, the grading company's app handles submitting and tracking, and scanner apps identify cards and show their values. Ten options follow, in no particular order, each described from its own page.
Before a card goes off to be graded, collectors want a feel for its condition. That's where the apps come in, though they don't all do the same job, and their names don't make it obvious which is which.
These ten are alphabetical and in no particular order. Each description comes from the app's own website or App Store listing, read as of Nov 2026. Nothing here says how close an app's estimate will be to a real grade, or whether a card's worth grading at all: that's your call.

Ten apps for card collectors
Card Grading AI
Best for: Photographing the front and back of a card to review centering, corners, edges and surface, with an estimated grade and four subgrades.
CardGrade
Best for: Collectors weighing up a submission, from a site that describes AI pre-grading across inspection zones and a tool for estimating likely PSA grades.
CardGrader
Best for: Pointing your phone at a card for an instant AI grade, with corners, edges, surface and centering marked on the card itself.
Centering50
Best for: iPhone users checking centering ratios before grading, from an app that says it's built for PSA and BGS centering.
Collectr
Best for: Trading card game collectors tracking a portfolio, adding cards with the camera and following market value for cards and sealed boxes.
CollX
Best for: Sports card collectors who want to snap a photo, see what a card's worth, and buy, sell or trade with other collectors in the same app.
Dex
Best for: Pokémon collectors chasing master sets, who want to scan cards, track a collection, check current values and sort cards into custom folders.
Ludex
Best for: Scanning sports cards and trading card games to identify them, then organising the collection and building a listing to sell.
PSA App
Best for: Sending cards to PSA, since the grading company's own app lets you scan, submit, track and organise graded and ungraded cards.
TCGrader
Best for: Pokémon fans wanting an AI grade, from a site that also covers sports cards, Magic, Yu-Gi-Oh! and Lorcana and lets you buy and sell cards.
Pre-grade, submit or scan?
Read the app pages side by side and three kinds appear. The first group estimates a grade from your own photos. CardGrader's page is titled 'AI Card Grading App' and says 'point your phone at a card for an instant AI grade'; CardGrade's title is 'AI Card Grading Online - Pre-Grade Before PSA'; TCGrader's is 'Free Pokémon AI Card Grading'; Card Grading AI's App Store listing says 'Estimate your card's grade before you submit it for professional grading'; and Centering50 is a 'TCG & Sports Card Grading Tool'.
The second is the grading company's own app. PSA's app page says 'Track, organize, submit, and sell graded and ungraded cards', so it's built around the submission itself rather than a guess at the grade.
The third group is scanners built around identifying cards and their values. Ludex's page is titled 'Sports Card and TCG Scanner', Collectr lets you 'Add any card with your camera', CollX says 'Scan sports cards to find out what they're worth', and Dex says 'Instantly scan cards, track your collection, check current values'.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
That's the split a collector wouldn't guess. Five of these estimate a grade from photos you take before you submit, one belongs to the grading company and is about sending cards in and tracking them, and the other four are built around scanning and values rather than grading.
Getting better photos for a pre-grade
Apps that estimate a grade can only work from the photos you give them. A few habits help with any of them:
- Shoot each side flat and square to the camera, so the borders sit evenly in the frame.
- Use soft, even light to keep glare off the surface and any holo foil.
- Take the card out of its sleeve or top loader if the app asks for a bare card.
- Wipe your lens, and dust the card gently, before you shoot.
- Photograph both sides, because corner, edge and surface wear shows on the back too.
What a pre-grade can't tell you
An app's estimate is the app's view, not a grade. Only the grading company grades the card, and its own standards decide the result. Treat a pre-grade as a way of spotting obvious problems, such as off-centre borders or a dinged corner, before you decide what to send.
If you're selling rather than grading, my guide to selling through eBay covers the selling side, and my breakdown of how much eBay takes explains what comes off a sale.
Five questions to ask a grading or scanner app
- Does it estimate a grade, or only identify the card?
- Which card games and sports does it cover?
- Does it check centering, corners, edges and surface separately?
- Can I keep a history of the cards I've checked?
- Is it on iPhone, Android or the web?

My advice on choosing a card grading app
Decide which question you're asking. If it's 'what condition is this card in?', try one of the photo pre-grading apps and photograph carefully. If you're sending cards in, the grading company's own app keeps the submission in one place. If you want to know what you own and keep it organised, a scanner app does that job. Using one of each is a sensible way to cover all three.

Frequently asked questions
What does a card grading app do?
It depends on the app. Some estimate a grade from photos of your card before you submit it, the grading company's own app handles submitting and tracking, and scanner apps identify cards and show their values.
Is an AI grade the same as a real grade?
No. An app's grade is an estimate from photos. Only a grading company grades a card, using its own standards, so treat an app's result as a guide to condition rather than the final word.
Can I submit cards to PSA through an app?
PSA's own app page says you can scan, submit and track cards through it. Check the app for the services available where you live before you send anything.
What's the difference between a grading app and a card scanner?
A grading app looks at a card's condition and estimates a grade. A scanner app identifies the card and is built around tracking your collection and its values. Some apps include a bit of both, so read the maker's page.
Do these apps work for Pokémon and sports cards?
Several cover both. Some pages name Pokémon and other trading card games, some focus on sports cards, and a couple are built for Pokémon collectors in particular. Check the card types each app lists.
How do I take good photos for an AI grade?
Shoot each side flat and square, use even light without glare, and photograph the front and back. A clean lens and a bare card help the app see the borders and corners clearly.
