# Quento vs Sudoku

The clearest difference is ads: Quento at none against Sudoku's shown. Quento also leads on update cadence (every 3 weeks vs every 6 months) and device support (3 vs 1). Sudoku's advantage is rating (4.6 vs 4.3) and ratings volume (58 vs 9). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. Quento sells 1 one-off in-app purchase and Sudoku sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Sudoku holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Sudoku has 58 ratings behind it against 9, so its average is the more settled of the two. Written reviews point the same way: 77% of Quento's written reviews are positive against 84% of Sudoku's.

Quento ships an update every 3 weeks, Sudoku every 6 months. The most recent releases landed on October 24, 2026 and October 29, 2026 respectively.
