# 知识星球 vs e签盾

The clearest difference is review sentiment: e签盾 at 100% against 知识星球's 48%. e签盾 also leads on rating (5.0 vs 4.7). 知识星球's advantage is update cadence (every 10 days vs every 2 months) and ratings volume (1.3K vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. 知识星球 sells 14 one-off in-app purchases and e签盾 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

e签盾 holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: 知识星球 has 1.3K ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 48% of 知识星球's written reviews are positive against 100% of e签盾's.

知识星球 ships an update every 10 days, e签盾 every 2 months. The most recent releases landed on October 16, 2026 and October 13, 2026 respectively.
