Sudoku Scan&Solve is made for helping you solving Sudoku puzzles. It scans Sudokus from paper or images, recognizing machine written numbers, and being able to learn handwritings as well. Having scanned a Sudoku, you can let it solve single cells, rows, columns or 3x3 boxes, tell you where a number is in a row, column or box, or solve the puzzle as a whole. As Sudoku Scan&Solve can also create Sudokus, you can also just use it as a simple Sudoku App that always tells you if you've made a mistake and helps you when you get stuck.
Remarks to Sudoku Scanning:
Recognition of Sudokus from camera runs on older devices, but works better the newer the device. If your device does not have a camera you can still scan images from your photo album, or use Sudoku Scan&Solve as a simple Sudoku App.
(Thanks to OpenCV for providing a framework that makes life easier when programming the recognition of Sudokus.)
