The application allows to capture a grid from its own camera (‘CAMERA’ menu) or to select a grid among the smartphone existing files (‘FILE’ menu), for example files coming from ‘DCIM’, in .jpg or .png formats. The grid image must have been captured in portrait orientation. Once the grid has been chosen, the ‘Solve’ button allows to get the solution.
