# Duolingo vs كتبي Kutubee

The clearest difference is rating: Duolingo at 4.7 against كتبي Kutubee's 4.0. Duolingo also leads on monetization model (free with in-app purchases vs subscription) and ratings volume (5.5M vs 427). كتبي Kutubee's advantage is ads (none vs shown) and iOS requirement (15.1 vs 17.0). On price, in-app purchases 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 كتبي Kutubee sells 8 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

Duolingo holds the better App Store score, 4.7 against 4.0. That said, the two scores are not equally well evidenced: Duolingo has 5.5M ratings behind it against 427, 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 43% of كتبي Kutubee's.

Duolingo ships an update weekly, كتبي Kutubee fortnightly. The most recent releases landed on September 25, 2026 and September 21, 2026 respectively.
