Excellent interface with powerful solver that provides hints. Extensive tutorial material to help interpret the hints and learn. Can take any muzzle as input from camera or puzzle string. Beautiful work with thousands of puzzles at each difficulty; much harder puzzles available than ordinary sudoku apps.

So far this is the best Sudoku app I’ve ever used. I like to solve paper books but can’t always carry them. Now I can save some and do them on my waiting time.
