# CoStudy(HD) vs 笔袋

The clearest difference is rating: 笔袋 at 4.9 against CoStudy(HD)'s 4.3. 笔袋 also leads on update cadence (every 5 days vs monthly) and device support (3 vs 1). On price, review sentiment, ratings volume and ads there is nothing between them.

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

笔袋 holds the better App Store score, 4.9 against 4.3. Both are backed by a comparable volume of ratings — 36 and 57 respectively. Written reviews complicate that: 94% of CoStudy(HD)'s written reviews are positive against 92% of 笔袋's, so the app with the better star average is not the one people write more warmly about.

CoStudy(HD) ships an update monthly, 笔袋 every 5 days. The most recent releases landed on November 3, 2026 and November 7, 2026 respectively.
