# Sudoku vs Study Bully

The clearest difference is rating: Study Bully at 5.0 against Sudoku's 4.1. Study Bully also leads on monetization model (freemium vs subscription). Sudoku's advantage is ratings volume (4.3K vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Sudoku sells 10 in-app purchases, starting at $2.99 per month and Study Bully sells 6 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.

Study Bully holds the better App Store score, 5.0 against 4.1. That said, the two scores are not equally well evidenced: Sudoku has 4.3K ratings behind it against 1, so its average is the more settled of the two.

Sudoku ships an update monthly, Study Bully every 2 months. The most recent releases landed on October 22, 2026 and October 1, 2026 respectively.
