# Prep vs Cây Study

The clearest difference is ads: Cây Study at none against Prep's shown. Cây Study also leads on rating (5.0 vs 4.6) and review sentiment (100% vs 86%). Prep's advantage is ratings volume (120 vs 1) and update cadence (every 5 days vs every 2 weeks). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Prep sells 64 one-off in-app purchases and Cây Study sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

Cây Study holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Prep has 120 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 86% of Prep's written reviews are positive against 100% of Cây Study's.

Prep ships an update every 5 days, Cây Study every 2 weeks. The most recent releases landed on September 25, 2026 and September 26, 2026 respectively.
