# Duolingo vs LANG

The clearest difference is ads: LANG at none against Duolingo's shown. LANG also leads on iOS requirement (15.0 vs 17.0). Duolingo's advantage is ratings volume (5.5M vs 12K) and chart position (#1 vs unranked). On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. Duolingo sells 16 in-app purchases, starting at $9.99 per month and LANG sells 8 in-app purchases, starting at $3.49 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 4.6 for LANG. That said, the two scores are not equally well evidenced: Duolingo has 5.5M ratings behind it against 12K, 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 72% of LANG's.

Both ship on a similar rhythm, roughly weekly. Both last shipped on September 25, 2026.
