Hi Product Hunt — I built Squoku because a finished Sudoku is a small victory, and that result should be worth keeping instead of disappearing when the paper is folded away. The flow is: • point an iPhone or iPad camera at a printed 9×9 Sudoku • review only the clues that need attention • confirm that the puzzle has one unique solution • see the missing digits aligned with the original grid • open, copy, share, or revisit a clean completed board Scanning, clue review, solving, History, and result generation happen on the device. Squoku requires no account and does not upload the puzzle or camera content. Two solution reveals are included. After that, you can reveal one confirmed puzzle with a small one-time purchase or unlock new puzzles forever with Squoku Pro. There is no subscription. I’d especially value feedback on the clue-review step and whether local History makes the completed puzzle feel worth remembering.
