# PureLibro vs 洞识：15分钟摘要

The clearest difference is rating: PureLibro at 4.6 against 洞识：15分钟摘要's 3.7. PureLibro also leads on ratings volume (362 vs 3) and review sentiment (77% vs 67%). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. PureLibro sells 6 in-app purchases, starting at $0.99 per month and 洞识：15分钟摘要 sells 5 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

PureLibro holds the better App Store score, 4.6 against 3.7. That said, the two scores are not equally well evidenced: PureLibro has 362 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 77% of PureLibro's written reviews are positive against 67% of 洞识：15分钟摘要's.

PureLibro ships an update every 10 days, 洞识：15分钟摘要 weekly. The most recent releases landed on September 26, 2026 and September 17, 2026 respectively.
