Card Grid Math

Point the camera at your 12 cards at the end of a round, snap, fix any misreads, read off the total. Pass the phone.

Frequently asked

Why does the app want camera access?

That's how it reads your cards. Everything is processed on your phone; photos are never stored or uploaded. See the privacy policy.

A card was read wrong. Now what?

Tap it on the review screen and pick the right value — the total updates instantly. Cards the app wasn't sure about are flagged so you know where to look first.

Tips for a clean scan?

Shoot from roughly above the hand with all 12 cards in frame, in decent light. A card still face down? Tap its spot and choose the face-down chip.

Does it keep score across rounds?

No — by design. Card Grid Math totals one hand at a time and keeps no score history. Pencil and paper still own the scoresheet.

Does it work offline?

Yes. Scanning and totals work completely offline.
