Use your smartphone to measure an object with the iPin Spatial Ruler Pro Smartphone Laser Ruler. Offering fast and accurate laser measuring, this ruler allows you to shoot first and measure later. Compatible with iOS and Android devices, the laser ruler uses your camera to measure the distance, dimensions, and line of an object with just one shot. To use the ruler, attach the iPin Pro to the back of your smartphone and turn on the iPin app. Then aim it at any object you want to measure and take a photo with your smartphone camera. The picture will contain all the measurements you’re after. You can also adjust the length, width, height, and depth manually by using your fingers. Furthermore, the iPin Pro doubles as a laser range finder, allowing you to use it on its own to measure distances.
