QuadCropper vs Ugokist

This app contains a Photos extension to crop and deskew rectangles in a photo. Since the rectangles may be skewed by perspective, the cropping tool allows individual placement of the four corners of the 2D quadrilateral -- and then deskews the contained rectangle. This is useful for business cards or slides or book covers or the like which have been photographed at an angle. The app mimics the functionality of the Photos extension and can access the Photos library or the camera to get an image. One can also crop the image from any file. Unless the image is retrieved from the Photos library, the app will store the cropped image to a user-selected file. Corners can be nudged by tapping on the corner circles. The corner will move by a pixel in the direction of the quadrant of the circle that was tapped on.
