Verdict

The call

The clearest difference is ads: Sudoku at none against Sudoku + Auto's shown. Sudoku also leads on ratings volume (1.1K vs 63) and review sentiment (95% vs 85%). Sudoku + Auto's advantage is update cadence (every 5 weeks vs every 3 months) and iOS requirement (13.0 vs 15.6). On price, rating, in-app purchases and monetization model there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Sudoku sells 11 one-off in-app purchases and Sudoku + Auto sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Sudoku holds the better App Store score, 4.8 against 4.6.

UpkeepUpdate frequency

Sudoku ships an update every 3 months, Sudoku + Auto every 5 weeks. Both last shipped on October 24, 2026.
