Verdict

The call

The clearest difference is review sentiment: AI Dictionary Translator at 100% against Duolingo's 65%. Duolingo's advantage is ratings volume (5.5M vs 137) and rating (4.7 vs 4.5). On price, update cadence, ads and in-app purchases 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

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Duolingo sells 16 in-app purchases, starting at $9.99 per month and AI Dictionary Translator sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Duolingo holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Duolingo has 5.5M ratings behind it against 137, so its average is the more settled of the two. Written reviews complicate that: 65% of Duolingo's written reviews are positive against 100% of AI Dictionary Translator's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Duolingo ships an update weekly, AI Dictionary Translator every 4 days. The most recent releases landed on September 24, 2026 and September 21, 2026 respectively.
