Sudoku Buddy by Freevia

The joy is in
figuring it out.

Keep your pencil. Keep your puzzle. Get a little help when you need it.

Scan a standard 9×9 Sudoku on paper—including the answers you’ve already written. Check the reading, see where you may have gone wrong, or ask for a hint that explains the next move.

Android 1.0.0 (build 132) is available to invited internal testers with Android 8.0+ and a camera. The production release is in Google review; the public Play listing may not open until approval.
