# 暗礁助手 vs 知行学伴

The clearest difference is iOS requirement: 知行学伴 at 15.0 against 暗礁助手's 17.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. 暗礁助手 sells 3 in-app purchases, starting at $0.99 per month and 知行学伴 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
