# 洞识：15分钟摘要 vs Readingo

The clearest difference is rating: Readingo at 4.8 against 洞识：15分钟摘要's 3.7. Readingo also leads on review sentiment (93% vs 67%) and ratings volume (113 vs 3). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. 洞识：15分钟摘要 sells 5 in-app purchases, starting at $4.99 per month and Readingo sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

Readingo holds the better App Store score, 4.8 against 3.7. That said, the two scores are not equally well evidenced: Readingo has 113 ratings behind it against 3, so its average is the more settled of the two. Written reviews point the same way: 67% of 洞识：15分钟摘要's written reviews are positive against 93% of Readingo's.

Both ship on a similar rhythm, roughly weekly. The most recent releases landed on September 17, 2026 and September 23, 2026 respectively.
