Measure your cards. Don't guess. Bind measures how well a trading card is centered — the left/right and top/bottom margins, to a tenth of a percent. BUILT FOR ACCURACY • A spirit level keeps the phone parallel to the card, so the shot is square. • Bind finds the card's edges for you, then you refine each corner at up to 12x. • Shot at an angle? Bind corrects the perspective mathematically, so the numbers hold even when the photo isn't perfectly flat. SEE WHAT THE NUMBERS MEAN The margin between the cut line and the print frame is shaded — the wider side fills in, so you see which way a card is off at a glance. KEEP THEM TOGETHER Every measurement lands in your Binder with its photo and outlines. Track how many of your cards fall inside the published 60/40 guideline. COMPARE WITH OTHER COLLECTORS Post a card and see where it ranks against every other copy of the same card. One reaction: Well-centered. WHAT BIND DOES NOT DO • No grade predictions. Centering is one of several things graders score; we show the measurement and the published guidelines, nothing more. • No prices, no trading, no location.
