Snap a sudoku from any newspaper or book and check your handwritten answers in seconds. Right cells turn green, wrong ones red. Works offline, nothing leaves your phone. Know if you got every cell right. Even your handwriting. Even mid-puzzle. Snap a sudoku from any newspaper, puzzle book, or screenshot. Your pencil answers turn green when right, red when wrong. No answer key, no eraser, no retyping digits. Works on the plane, on the train, anywhere. WHY IT'S DIFFERENT - Know if you got it right. Most scanners only see printed digits. This one checks your handwritten answers too. - Never get stuck. Reveal one cell, or the whole grid, in a tap. - 100% on-device. No internet, no account, no server. Photos and grids never leave your iPhone. - Two-second scans. Point, tap, done. No spinner. - Works on real paper. Folded newsprint, puzzle-book curl, dim cafe light. The grid detector handles it. - Camera or library or keyboard. Scan live, pick a screenshot, or type the puzzle in by hand. HOW IT WORKS Printed clues stay neutral. Correct answers glow green. Wrong answers flag red. Tap any empty cell to reveal one number, or solve the whole grid at once. MADE FOR - Solvers double-checking the last cell before claiming victory. - Parents and teachers verifying kids' work without the answer key. - Puzzle-book readers who want a safety net for pencil and paper. - Travelers solving puzzles offline on planes and trains.
