# 阳光自律 vs CoStudy

The clearest difference is rating: CoStudy at 4.8 against 阳光自律's 2.3. CoStudy also leads on review sentiment (93% vs 67%) and ratings volume (72 vs 6). 阳光自律's advantage is ads (none vs shown) and iOS requirement (9.0 vs 13.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. 阳光自律 sells 3 in-app purchases, starting at $0.99 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.

CoStudy holds the better App Store score, 4.8 against 2.3. That said, the two scores are not equally well evidenced: CoStudy has 72 ratings behind it against 6, so its average is the more settled of the two. Written reviews point the same way: 67% of 阳光自律's written reviews are positive against 93% of CoStudy's.

阳光自律 ships an update monthly, CoStudy fortnightly. The most recent releases landed on November 3, 2026 and November 12, 2026 respectively.
