# Duolingo vs Trilingo Vocabulary Builder

The clearest difference is rating: Duolingo at 4.7 against Trilingo Vocabulary Builder's 4.0. Duolingo also leads on update cadence (every 5 days vs every 5 weeks) and ratings volume (5.5M vs 139). Trilingo Vocabulary Builder's advantage is review sentiment (77% vs 65%) and iOS requirement (10.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Duolingo sells 16 in-app purchases, starting at $9.99 per month and Trilingo Vocabulary Builder sells 10 in-app purchases, starting at $9.49 per month. Whichever you choose, the download price is not the number that matters.

Duolingo holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Duolingo has 5.5M ratings behind it against 139, so its average is the more settled of the two. Written reviews complicate that: 65% of Duolingo's written reviews are positive against 77% of Trilingo Vocabulary Builder'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, Trilingo Vocabulary Builder every 5 weeks. The most recent releases landed on October 30, 2026 and October 22, 2026 respectively.
