Save time, money, and headaches by eliminating the need to do complex math on the job. Carta is the first digital measuring wheel to virtually map blueprints of outdoor spaces with measurements in real time straight to your smartphone. Easily calculate distance, perimeter, & area by simply wheeling Carta around the space. Save important notes, images, and videos on any project to use later or share with others for fast collaboration. After mapping out a blueprint use Carta’s Guide Mode to revisit selected marks.
