It is so powerful to make measuring job done faster and without any hassle. Three easy steps to work 1. AIM: Turn on the App and simply attach the iPin Spatial Ruler Pro on the back of your smartphone. Aim the phone camera at the horizontal ground near the object you want to measure. 2. Shoot: Take a photo using your smartphone camera. 3. Size: The photo you took contains all measurements data. Adjust the 3-axis points manually with your fingertips to measure the object you want. Why we developed it? It was first developed to resolve the "inconveniences" in the measurement with traditional practice.

With smartphone camera and iPin Spatial Ruler Pro together, you are free from moving point to point repeatedly as in the traditional measuring process. You don’t need to climb up a ladder or kneel down to touch the ground just to get some data. Moreover, iPin Spatial Ruler Pro App uses phone camera to take photo and saves the measuring data with the image in the phone. So, you can re-measure any part of that photo with fingertips whenever needed. Features: Shoot first and measure later With iPin Spatial Ruler Pro App, measured data is saved within the photo taken. You can measure any object in the saved photo at your fingertips whenever needed. Features: 3-axis measuring The ceiling corner area is always difficult to reach and measure.
