# Duolingo vs Modal Math

The clearest difference is ads: Modal Math at none against Duolingo's shown. Modal Math also leads on rating (5.0 vs 4.7) and iOS requirement (15.1 vs 17.0). Duolingo's advantage is update cadence (weekly vs every 5 weeks) and ratings volume (5.5M vs 2). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Duolingo sells 16 in-app purchases, starting at $9.99 per month and Modal Math sells 2 in-app purchases, starting at $24.99 per month. Whichever you choose, the download price is not the number that matters.

Modal Math holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Duolingo has 5.5M ratings behind it against 2, so its average is the more settled of the two.

Duolingo ships an update weekly, Modal Math every 5 weeks. The most recent releases landed on September 27, 2026 and June 24, 2026 respectively.
