This app records the perspective calculated from the iPhone's tilt angle at the time of shooting directly onto the photo. In the current version, you can draw horizontal lines, vertical lines, 45° lines, as well as grids, cubes, and rectangular solids. When you want to find the perspective of a slope, just place your iPhone on the inclined surface and press the SetTilt button!
