Verdict
The clearest difference is update cadence: Sudoku by Joseph at every 5 days against Sudoku HD!'s every 6 months. Sudoku by Joseph also leads on rating (4.7 vs 4.5) and ratings volume (2.4K vs 707). Sudoku HD!'s advantage is review sentiment (87% vs 73%) and iOS requirement (12.0 vs 17.6). On price, ads, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Sudoku HD! sells 11 one-off in-app purchases and Sudoku by Joseph sells 5 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.
Sudoku by Joseph holds the better App Store score, 4.7 against 4.5. Both are backed by a comparable volume of ratings — 707 and 2.4K respectively. Written reviews complicate that: 87% of Sudoku HD!'s written reviews are positive against 73% of Sudoku by Joseph's, so the app with the better star average is not the one people write more warmly about.
Sudoku HD! ships an update every 6 months, Sudoku by Joseph every 5 days. Both last shipped on September 19, 2026.
