Every professional grading service evaluates both faces, and the back is often where a card loses points — centering and edge wear frequently differ from the front. Grading only the front would systematically over-report your card's condition.

GradeLab measures centering to the pixel, which is precise and repeatable. Corners, edges, and surface are assessed by machine-learning models, which are good but not infallible. Every result carries a confidence score, and when confidence is low we show a range instead of a single number. This is an estimate to help you decide what's worth submitting — not a substitute for professional grading.

No. GradeLab is an independent tool and is not affiliated with, endorsed by, or connected to PSA, BGS, SGC, CGC, or any other grading service. Our estimates have no standing with those companies and cannot be used in place of their certification.

Grading works identically for every card — it needs no database at all. Identification is different: Pokémon and Yu-Gi-Oh! have card data we can use under a proper licence, while Magic and sports cards don't have a freely licensable source. For those we read the text off the card and ask you to confirm. Each confirmation improves matching for everyone.

GradeLab won't shoot until lighting, focus, angle, and steadiness are all good enough. A poor capture produces a confidently wrong grade, which is worse than no grade at all. Follow the on-screen prompt — it always shows the single most important thing to fix.

Yes. Sleeves and toploaders refract light at the border and corrupt centering measurements. GradeLab tries to detect this and will warn you.

Bright, even, indirect light. Avoid direct sunlight and single overhead spotlights, which create glare on glossy cards. GradeLab uses your flash for part of the scan — that's intentional, and it's how surface scratches are separated from print lines.

No. All analysis happens on your iPhone. Photos stay on your device and, if you use iCloud, sync to your own private iCloud account that we cannot access.

Subscriptions are managed by Apple, not by us. Open the Settings app on your iPhone, tap your name, then Subscriptions, and select GradeLab. Cancelling there stops the renewal; you keep access until the end of the period you've paid for.
