# ClassDojo vs Duolingo

The clearest difference is ads: ClassDojo at none against Duolingo's shown. ClassDojo also leads on update cadence (every 2 days vs weekly). Duolingo's advantage is chart position (#1 vs #4). On price, rating, review sentiment and ratings volume there is nothing between them.

Both are free to download. ClassDojo sells 17 in-app purchases, starting at $6.99 per month and Duolingo sells 16 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for ClassDojo against 4.7 for Duolingo. Both are backed by a comparable volume of ratings — 4.1M and 5.5M respectively. Written reviews are what separate them: 69% of ClassDojo's written reviews are positive against 65% of Duolingo's.

ClassDojo ships an update every 2 days, Duolingo weekly. Both last shipped on September 24, 2026.
