Are you familiar with terms like "X-Wing", "2-String Kite", or "Locked Candidates"? If yes, Smart Sudoku is for you. If not, even more so.
Unlike most Sudoku apps, Smart Sudoku helps you solve tough puzzles by not simply revealing cell solutions, but by giving you professional tips. It tells you what patterns to look for in order to eliminate candidates.
Smart Sudokus' unique scoring system ranks your solution not by the time you spent, but by how efficiently you solved the puzzle.
Smart Sudoku comes with hundreds of challenging puzzles built-in. Copying a puzzle from a newspaper is a breeze – think of typing in a few phone numbers.
"Excellent. Very simple to enter puzzles from the newspaper. Candidate numbers are displayed, allowing solutions to really tough puzzles to be solved without the laborious job of setting up candidates." (UK user)

“Not assessed” means we could not measure it. It is never a zero and never a pass.
No package has been scanned for this app, so nothing is published about what it ships. That is an absence of evidence, not a finding.

Each store’s release notes, as the developer wrote them. They are the developer’s words, not ours.
• The progress bar now shows how far the puzzle has been solved. Previously, the display referred to the highest score achieved. • By quadruple tapping the background, the puzzle format can temporarily be switched to using "0" instead of "." for empty cells. This facilitates the exchange of puzzles on the Internet, e.g. Sudoku solvers. • Adjustments for iOS 26. Bug fix: In iOS 26, the "Check" button didn't work anymore.

Not yet tested. No analysis has been published for this app, so there is no method to describe for it yet. A missing label is not a clean bill of health: it means nothing has been read, not that nothing is wrong.
