Verdict
The clearest difference is ratings volume: Duolingo at 5.5M against Learn German AI's 368. Duolingo also leads on update cadence (weekly vs monthly) and chart position (#1 vs unranked). Learn German AI's advantage is review sentiment (75% vs 65%) and iOS requirement (15 vs 17.0). On price, rating, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Duolingo sells 16 in-app purchases, starting at $9.99 per month and Learn German AI sells 5 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.
On the App Store both sit at effectively the same score — 4.7 for Duolingo against 4.8 for Learn German AI. That said, the two scores are not equally well evidenced: Duolingo has 5.5M ratings behind it against 368, so its average is the more settled of the two. Written reviews are what separate them: 65% of Duolingo's written reviews are positive against 75% of Learn German AI's.
Duolingo ships an update weekly, Learn German AI monthly. Both last shipped on September 24, 2026.
