Build a read once · use it every hand
Saved on this device only — nothing is uploaded anywhere. A profile stores what kind of hands this player shows up with, one position at a time; you don't need to fill in every seat before it's useful.
Pick the seat you've observed them from. The green dot means that seat already has a saved range.
Tap cells to paint · maroon = painted & typical · gold = painted & wider than typical · tan outline = typical but not painted
Changes save immediately — there's no separate save step.
