Verdict
The clearest difference is update cadence: 4You at daily against Cây Study's every 2 weeks. 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.
