# Duolingo vs AI Language Practice

The clearest difference is ads: AI Language Practice at none against Duolingo's shown. AI Language Practice also leads on update cadence (every 3 days vs weekly). Duolingo's advantage is ratings volume (5.5M vs 232) and rating (4.7 vs 4.5). On price, review sentiment, 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 AI Language Practice sells 42 in-app purchases, starting at $14.00 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 5.5M ratings behind it against 232, so its average is the more settled of the two. Written reviews complicate that: 65% of Duolingo's written reviews are positive against 66% of AI Language Practice's, so the app with the better star average is not the one people write more warmly about.

Duolingo ships an update weekly, AI Language Practice every 3 days. The most recent releases landed on September 25, 2026 and September 21, 2026 respectively.
