# CoStudy vs 小律

The clearest difference is ads: 小律 at none against CoStudy's shown. 小律 also leads on update cadence (every 4 days vs every 3 weeks) and rating (5.0 vs 4.8). CoStudy's advantage is ratings volume (72 vs 4) and iOS requirement (13.0 vs 16.1). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. CoStudy sells 10 in-app purchases, starting at $3.99 per month and 小律 sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

小律 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 4, so its average is the more settled of the two. Written reviews point the same way: 93% of CoStudy's written reviews are positive against 97% of 小律's.

CoStudy ships an update every 3 weeks, 小律 every 4 days. Both last shipped on November 3, 2026.
