Measure your card's centering in seconds — before you pay a grading fee. Centering is the one grading factor you can check yourself. Photograph a card, and the app finds the borders and gives you the exact left/right and top/bottom centering percentages and ratios: the same numbers PSA, BGS, SGC, CGC and TAG look at when they assign a grade. MEASURE CENTERING IN SECONDS • Automatic border and edge detection, processed on your device • Exact L/R and T/B percentages plus 55/45-style centering ratios • Drag the guides by hand for miscuts, full-bleed borders and odd cuts • Works with any card: Pokemon, TCG, baseball, basketball, football, hockey, soccer and vintage KNOW THE GRADE BEFORE YOU SUBMIT • Built-in centering standards for PSA, BGS, SGC, CGC and TAG • Every grade tier from Gem Mint 10 down, with the centering it requires • Decide which cards are worth the grading fee and which are not VISUALIZE CENTERING • Move the sliders and see what 60/40 or 55/45 actually looks like on a card • Train your eye before you buy, trade or submit YOUR CARD COLLECTION • Save each measured card with its photo, result, grade and notes • Reopen any measurement later and track your whole collection • Share a result with a trade partner or your grading group WHO IT IS FOR Collectors preparing a submission, sellers pricing a slab-worthy card, breakers checking pulls, and anyone who has ever sent a card in and got a lower grade back because of centering.
