Verdict

The call

The clearest difference is ads: Conjuu at none against Duolingo's shown. Conjuu also leads on review sentiment (78% vs 65%) and device support (4 vs 2). Duolingo's advantage is ratings volume (5.6M vs 59) and update cadence (every 5 days vs every 3 weeks). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Duolingo sells 10 in-app purchases, starting at $9.99 per month and Conjuu sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

On the App Store both sit at effectively the same score — 4.7 for Duolingo against 4.6 for Conjuu.

Written reviews are what separate them: 65% of Duolingo's written reviews are positive against 78% of Conjuu's.

UpkeepUpdate frequency

Duolingo ships an update every 5 days, Conjuu every 3 weeks. The most recent releases landed on November 11, 2026 and November 1, 2026 respectively.
