# 好柿花生 vs CoStudy

The clearest difference is ratings volume: CoStudy at 72 against 好柿花生's 1. 好柿花生's advantage is update cadence (every 10 days vs every 3 weeks) and iOS requirement (11.0 vs 13.0). On price, rating, ads and in-app purchases there is nothing between them.

Both are free to download. 好柿花生 sells 10 in-app purchases, starting at $0.49 per month and CoStudy sells 10 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

好柿花生 holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: CoStudy has 72 ratings behind it against 1, so its average is the more settled of the two.

好柿花生 ships an update every 10 days, CoStudy every 3 weeks. The most recent releases landed on November 3, 2026 and November 7, 2026 respectively.
