# Cây Study vs 4You

The clearest difference is update cadence: 4You at daily against Cây Study's fortnightly. 4You also leads on ratings volume (98 vs 1). Cây Study's advantage is rating (5.0 vs 4.7) and review sentiment (96% vs 78%). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Cây Study sells 10 one-off in-app purchases and 4You sells 10 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.

Cây Study holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: 4You has 98 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 96% of Cây Study's written reviews are positive against 78% of 4You's.

Cây Study ships an update fortnightly, 4You daily. The most recent releases landed on October 30, 2026 and October 28, 2026 respectively.
