# iBuilder vs Sudoku

The clearest difference is rating: Sudoku at 5.0 against iBuilder's 2.2. Sudoku also leads on in-app purchases (none vs 1) and update cadence (every 4 weeks vs every 29 months). iBuilder's advantage is ads (none vs shown) and ratings volume (12 vs 2). On price and device support there is nothing between them.

Both are free to download. iBuilder sells 1 one-off in-app purchase. Sudoku asks for nothing beyond the download.

Sudoku holds the better App Store score, 5.0 against 2.2. That said, the two scores are not equally well evidenced: iBuilder has 12 ratings behind it against 2, so its average is the more settled of the two.

iBuilder ships an update every 29 months, Sudoku every 4 weeks. The most recent releases landed on June 11, 2026 and September 10, 2026 respectively.
