Don’t want to carry a tape measure in your pocket? With iPin Spatial Ruler, you won’t have to. It utilizes a patented “hybrid earphone plug” for keeping it inside iPhone’s earphone jack without affecting your phone functions. This is the world’s first spatial ruler for your smartphone. In addition to measuring the distance between an object and the phone, the iPin Spatial Ruler can determine the distance between two points on the image it captures, such as the length of a desk. iPin cleverly incorporates the zoom feature on the touchscreen to precisely dial in your measurements. It can measure distance and length in centimeters, meters, inches, and feet. iPin Spatial Ruler makes your iPhone into a lightning quick measuring tool. No complicated calibration for every measurement. Just point the laser and accurately measure anything from the size of a new couch to room dimensions. With the iPin Ruler App, you can save your measurement on your smartphone and easily share this information with family or colleagues, and re-measure objects using the “Editable” format. Measuring on the go has never been this easy. Just plug it into the headphone jack and you can measure pretty much anything.
