# 知乎 vs Echomelon

The clearest difference is ads: Echomelon at none against 知乎's shown. 知乎's advantage is chart position (#131 vs unranked) and iOS requirement (13.0 vs 15.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. 知乎 sells 13 in-app purchases, starting at $2.99 per month and Echomelon sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
