# Duolingo vs AI Dictionary Translator

The clearest difference is review sentiment: AI Dictionary Translator at 100% against Duolingo's 65%. Duolingo's advantage is ratings volume (5.6M vs 163) and rating (4.7 vs 4.5). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Duolingo sells 10 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.

Duolingo holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Duolingo has 5.6M ratings behind it against 163, 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.

Duolingo ships an update every 5 days, AI Dictionary Translator every 4 days. The most recent releases landed on November 6, 2026 and November 4, 2026 respectively.
