Rummy Calculator

Choose Gin Rummy or Rummy 500 first, then use a scanner tailored to that game. Rummy Calculator recognizes standard playing cards on your iPhone, lets you correct every result, and calculates the score without uploading photos.

GIN RUMMY
Scan a complete ten-card hand. The solver considers overlapping set and run choices together, finds the arrangement with the lowest deadwood, and shows whether the hand is Gin, ready to knock, or should keep drawing.

RUMMY 500
Scan the cards you melded and the cards left in your hand. Rummy Calculator adds melded card values, subtracts the hand penalty, records the round, and carries your cumulative total toward 500. Standard single-deck scoring is included, with an explicit low-Ace adjustment for A-2-3 runs.

VERIFY EVERY CARD
Use the live camera scanner, then correct any rank or suit directly before relying on the result.

PRIVATE BY DESIGN
Card recognition, scoring, and game history stay on your device. Rummy Calculator requires no account, advertising, analytics, or tracking.

Three successful scanned hands or rounds are free. Unlimited Scans is a one-time USD 0.99 equivalent purchase with no subscription.
