Verdict
The clearest difference is rating: Imprint at 4.8 against Sudoku's 4.1. Imprint also leads on update cadence (every 6 days vs monthly) and ratings volume (56K vs 4.1K). Sudoku's advantage is ads (none vs shown) and review sentiment (47% vs 38%). On price, in-app purchases, monetization model and device support 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. Imprint sells 14 in-app purchases, starting at $3.99 per month and Sudoku sells 10 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
Imprint holds the better App Store score, 4.8 against 4.1. That said, the two scores are not equally well evidenced: Imprint has 56K ratings behind it against 4.1K, so its average is the more settled of the two. Written reviews complicate that: 38% of Imprint's written reviews are positive against 47% of Sudoku's, so the app with the better star average is not the one people write more warmly about.
Imprint ships an update every 6 days, Sudoku monthly. The most recent releases landed on September 26, 2026 and September 25, 2026 respectively.
