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! You can choose from two saving methods: drawing the perspective overlay on the photo and saving it as one image, or saving the photo and perspective as separate images. * Before use, you need to configure the angle of view using an actual horizon line.
