About this app

"Could not detect the card." "Take it out of the sleeve." "Create an account first." "My saved measurements are gone." This app was built to answer those four. ■ You place the corners, so it always measures It does look for the card automatically, but only to put the handles somewhere sensible. You set the four corners yourself, so "it won't detect my card" simply cannot happen. ■ Shoot from any angle. Same numbers. The tilt is removed from the four corners and the card's real dimensions before anything is measured. No need to reshoot from directly above. It works through a sleeve. ■ See which side holds it back Colour marks whether the left/right or the top/bottom border is the one setting your ceiling. ■ No predictions. Just the ceiling. It returns how far centering alone could take a card — nothing more. Edges, corners and surface are not measured, so a real grade will land at or below what you see here. This app does not predict grades. ■ No photo? Type the numbers. Enter the four border widths from calipers or a ruler and you get the same answer. ■ Front and back Grading companies apply a different tolerance to the back. Measure both and the ceiling gets more accurate. ■ Stays on your phone Photos and records never leave the device. No account. No limit on how many times you measure. Everything exports in one file.

Momentum comes from crawler snapshots for the tracked storefront. “Viral growth signal” means unusually fast recent rating gains; it is an indicator, not download data.
