# Sudoku ▪ vs Calculuz

The clearest difference is update cadence: Calculuz at every 6 days against Sudoku ▪'s every 3 months. Calculuz also leads on rating (5.0 vs 4.7) and iOS requirement (12.0 vs 15.0). Sudoku ▪'s advantage is ratings volume (91 vs 3). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Sudoku ▪ sells 4 in-app purchases, starting at $1.49 per month and Calculuz sells 7 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Calculuz holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Sudoku ▪ has 91 ratings behind it against 3, so its average is the more settled of the two.

Sudoku ▪ ships an update every 3 months, Calculuz every 6 days. Both last shipped on October 24, 2026.
