Sudoku Note is a handwriting-first Sudoku app designed for calm, paper-like problem solving. Instead of tapping numbers on a keypad, users write numbers directly on the board using Apple Pencil or touch. You can erase, rewrite, and make small notes—just like solving Sudoku in a real notebook. Handwriting is the core interaction, not an optional feature. Puzzles are carefully curated by solving techniques, allowing users to focus on thinking and exploration rather than speed or pressure.

Hi Product Hunt 👋
I’m the maker of Sudoku Note.
I built this because solving Sudoku on paper always felt more thoughtful than tapping numbers on a screen. Writing, erasing, and making small notes helps me slow down and focus in a way most Sudoku apps don’t.
What started as a small handwriting experiment quickly became the core of the app. Writing numbers directly on the board changed how I think about puzzles, so I designed the entire experience around that interaction.
Sudoku Note is for people who like to think with their hands—especially Apple Pencil users who enjoy calm, focused problem solving.
Thanks for checking it out! Happy to answer any questions 🙌

I love this experience. This preserves the actual craft of the puzzle. Definitely a win for those of us who find handwriting more meditative than typing. Congrats on the launch!
