# Sudoku vs Stock Chart Simulator

The clearest difference is rating: Sudoku at 4.7 against Stock Chart Simulator's 3.5. Sudoku also leads on ratings volume (59K vs 2). Stock Chart Simulator's advantage is ads (none vs shown) and update cadence (every 2 days vs monthly). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Sudoku sells 10 in-app purchases, starting at $0.99 per month and Stock Chart Simulator sells 5 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Sudoku holds the better App Store score, 4.7 against 3.5. That said, the two scores are not equally well evidenced: Sudoku has 59K ratings behind it against 2, so its average is the more settled of the two.

Sudoku ships an update monthly, Stock Chart Simulator every 2 days. The most recent releases landed on November 9, 2026 and October 30, 2026 respectively.
