# Dịch Tiếng Anh KALA vs Cây Study

The clearest difference is ads: Cây Study at none against Dịch Tiếng Anh KALA's shown. Cây Study also leads on review sentiment (96% vs 71%) and rating (5.0 vs 4.7). Dịch Tiếng Anh KALA's advantage is ratings volume (1.8K vs 1). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Dịch Tiếng Anh KALA sells 4 in-app purchases, starting at $0.99 per month and Cây Study sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
