# Thai Dictionary + vs Duolingo

The clearest difference is update cadence: Duolingo at weekly against Thai Dictionary +'s every 2 months. Duolingo also leads on ratings volume (5.5M vs 424) and chart position (#1 vs unranked). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Thai Dictionary + sells 5 one-off in-app purchases 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 — 4.6 for Thai Dictionary + against 4.7 for Duolingo. That said, the two scores are not equally well evidenced: Duolingo has 5.5M ratings behind it against 424, so its average is the more settled of the two. Written reviews are what separate them: 71% of Thai Dictionary +'s written reviews are positive against 65% of Duolingo's.

Thai Dictionary + ships an update every 2 months, Duolingo weekly. The most recent releases landed on September 24, 2026 and September 25, 2026 respectively.
