As you lengthen the measuring tape, the measurement displays on screen. Tap a button to save. Or convert measurements quickly (from fractions to decimals, or inches to centimeters, for example) and calculate midpoints (great for helping to hang a picture). And no need to bend the tape when measuring into a corner—just select the back of the device as the starting point.
This digital measuring tape simplifies projects with less lunging for paper and pencil and less math to mess up.
