About this app

This is a free "Sudoku Input Editor" for inputting and solving Sudoku puzzles from books and newspapers. Simply input your paper Sudoku puzzles and receive assistance with solutions. It also supports creating, verifying, and checking your own Sudoku puzzles.
It will significantly improve your skills and reduce mistakes. The semi-automated note function eliminates the need for tedious initial note input and most note deletion tasks.
Users are responsible for deleting notes using tricks.
Entered puzzles can be saved with a name, allowing you to challenge the same puzzle multiple times.
Intermediate stages can also be saved with a different name, allowing you to start over from the middle.
Designed for self-solving, even with the support features, there's still a strong sense of accomplishment.
Recently, we added support for SF (Swordfish) and SD backup and restore functions for moving puzzles.
With your support, we plan to add an automatic problem import function using a camera in the future. It's also ideal for checking and studying your own puzzles.
Also, in the future, it may be possible to add a feature that provides questions within the app (if it can be linked to books).
