Verdict
The clearest difference is rating: Assimil at 4.4 against DK Illustrated Dictionary's 3.7. Assimil also leads on update cadence (every 4 days vs every 9 days) and ratings volume (29 vs 6). DK Illustrated Dictionary's advantage is in-app purchases (none vs 45) and review sentiment (67% vs 32%). On price, ads and device support there is nothing between them.

Both are free to download. Assimil sells 45 one-off in-app purchases. DK Illustrated Dictionary asks for nothing beyond the download.
Assimil holds the better App Store score, 4.4 against 3.7. Both are backed by a comparable volume of ratings — 29 and 6 respectively. Written reviews complicate that: 32% of Assimil's written reviews are positive against 67% of DK Illustrated Dictionary's, so the app with the better star average is not the one people write more warmly about.
Assimil ships an update every 4 days, DK Illustrated Dictionary every 9 days. The most recent releases landed on October 26, 2026 and October 24, 2026 respectively.
