Leftover Bricks?

Found a piece left over after building? This app helps you look for the steps where it may be used in your set. Enter your set number to check support. Photograph one piece and compare the suggested shapes and colors, or enter a part number from the instructions. When a matching record is available, review the step, booklet, page, and quantity, then open the instructions to check it yourself. Support is expanding set by set. Identification results and spare-part references are guides; check the physical piece and official instructions before drawing a conclusion.
