# 知乎 vs 库百汇

The clearest difference is in-app purchases: 库百汇 at none against 知乎's 17. 库百汇 also leads on ads (none vs shown). 知乎's advantage is update cadence (weekly vs every 3 months) and chart position (#144 vs unranked). On price, device support and iOS requirement there is nothing between them.

Both are free to download. 知乎 sells 13 in-app purchases, starting at $2.99 per month. 库百汇 asks for nothing beyond the download.

知乎 ships an update weekly, 库百汇 every 3 months. The most recent releases landed on October 24, 2026 and October 13, 2026 respectively.
