Stop guessing whether a card is worth grading. Take two photos to predict its grade and the odds of each outcome, see detected damage and measured centering, and estimate your profit after grading and selling fees. Evo was trained using cards from real cracked slabs. Use it to pre-grade cards, track submissions, track your gem rate, find potential grading opportunities, and monitor your collection value. TRAINED ON REAL SLABS We bought slabs graded by PSA, TAG, and CGC and cracked them open to train Evo’s model. Evo learns from cards that received real professional grades, helping it connect visible damage, centering, and condition with grading outcomes. Our current slab data covers PSA, TAG, and CGC grades 6–10, as well as CGC Pristine 10. SEE THE DAMAGE Any AI grading app can give you a number, but we believe it is important to explain why. Evo marks detected damage directly on you…
Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 8 screenshots above are Evo: AI Card Grading's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: Evo: AI Card Grading runs a mixed light-and-dark set where the background shifts from screenshot to screenshot (first shot #FC3C1C) — each image has to stand on its own, so the captions carry more of the story. The accent colour we picked up, #54E404, is the one to reuse for badges, arrows and highlighted words if you borrow this look. Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
