# Duolingo vs Earthlingo

The clearest difference is ads: Earthlingo at none against Duolingo's shown. Earthlingo also leads on iOS requirement (12.0 vs 17.0). Duolingo's advantage is update cadence (weekly vs every 5 weeks) and ratings volume (5.5M vs 66). On price, rating, review sentiment and in-app purchases there is nothing between them.

Both are free to download. Duolingo sells 16 in-app purchases, starting at $9.99 per month and Earthlingo sells 2 one-off in-app purchases. 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 66, so its average is the more settled of the two. Written reviews complicate that: 65% of Duolingo's written reviews are positive against 67% of Earthlingo's, so the app with the better star average is not the one people write more warmly about.

Duolingo ships an update weekly, Earthlingo every 5 weeks. The most recent releases landed on September 26, 2026 and June 9, 2026 respectively.
