Verdict

The call

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.

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.

ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

Imprint ships an update every 6 days, Sudoku monthly. The most recent releases landed on September 26, 2026 and September 25, 2026 respectively.
