# Duolingo vs Mondly

The clearest difference is ads: Mondly at none against Duolingo's shown. Duolingo's advantage is ratings volume (5.5M vs 33K) and chart position (#1 vs unranked). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. Duolingo sells 16 in-app purchases, starting at $9.99 per month and Mondly sells 8 in-app purchases, starting at $7.99 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 — 4.7 for Duolingo against 4.7 for Mondly. That said, the two scores are not equally well evidenced: Duolingo has 5.5M ratings behind it against 33K, so its average is the more settled of the two.

Duolingo ships an update every 6 days, Mondly fortnightly. Both last shipped on October 23, 2026.
