# 知乎 vs 知鱼

The clearest difference is ads: 知鱼 at none against 知乎's shown. 知乎's advantage is chart position (#136 vs unranked). On price, update cadence, in-app purchases and device support there is nothing between them.

Both are free to download. 知乎 sells 8 in-app purchases, starting at $2.99 per month and 知鱼 sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

知乎 ships an update weekly, 知鱼 fortnightly. The most recent releases landed on November 4, 2026 and October 30, 2026 respectively.
