Verdict

The call

The clearest difference is price: Binary Sudoku+ at Free against Duono's $2.99. Binary Sudoku+ also leads on rating (4.7 vs 4.0) and ratings volume (132 vs 1). Duono's advantage is review sentiment (83% vs 40%) and in-app purchases (none vs 6). On update cadence and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Binary Sudoku+ holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Binary Sudoku+ has 132 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 40% of Binary Sudoku+'s written reviews are positive against 83% of Duono's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Binary Sudoku+ ships an update every 10 days, Duono every 2 weeks. The most recent releases landed on September 5, 2026 and September 10, 2026 respectively.
