Sudoku Note – Handwriting-first Sudoku with Apple Pencil support

Summary: Sudoku Note is a Sudoku app centered on handwriting input using Apple Pencil or touch, enabling users to write, erase, and make notes directly on the board. It offers puzzles curated by solving techniques to encourage thoughtful, paper-like problem solving without speed pressure.

What it does

Users write numbers and notes directly on the Sudoku grid instead of tapping a keypad, with handwriting as the primary interaction. The app supports erasing and rewriting to mimic solving Sudoku on paper.

Who it's for

It targets users who prefer a tactile, thoughtful Sudoku experience, especially Apple Pencil users seeking calm and focused puzzle solving.

Why it matters

It addresses the lack of natural handwriting input in Sudoku apps, fostering deeper engagement and slower, more deliberate problem solving.
