# Duolingo vs Compy

The clearest difference is ads: Compy at none against Duolingo's shown. Compy also leads on iOS requirement (11.0 vs 17.0). Duolingo's advantage is update cadence (weekly vs every 4 months) and ratings volume (5.5M vs 6). 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 Compy sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Duolingo holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: Duolingo has 5.5M ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 65% of Duolingo's written reviews are positive against 50% of Compy's.

Duolingo ships an update weekly, Compy every 4 months. The most recent releases landed on September 26, 2026 and June 1, 2026 respectively.
