Verdict

The call

The clearest difference is price: Duolingo at Free against Korean Pro's $4.99. Duolingo also leads on ratings volume (5.6M vs 1) and update cadence (every 5 days vs every 3 weeks). Korean Pro's advantage is in-app purchases (none vs 28) and ads (none vs shown). On review sentiment there is nothing between them.

CostPrice · In-app purchases · Ads · Monetization

Duolingo is free to download; Korean Pro costs $4.99 up front. Duolingo sells 16 in-app purchases, starting at $9.99 per month. Korean Pro asks for nothing beyond the download.

ReceptionRating · Positive reviews · Number of ratings

Korean Pro holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Duolingo has 5.6M ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 65% of Duolingo's written reviews are positive against 57% of Korean Pro's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Duolingo ships an update every 5 days, Korean Pro every 3 weeks. The most recent releases landed on November 1, 2026 and October 30, 2026 respectively.
