# 极客时间 vs 沉浸单词

The clearest difference is in-app purchases: 沉浸单词 at none against 极客时间's 13. 沉浸单词 also leads on ads (none vs shown). 极客时间's advantage is device support (3 vs 1) and iOS requirement (10.0 vs 17.0). On price there is nothing between them.

Both are free to download. 极客时间 sells 13 one-off in-app purchases. 沉浸单词 asks for nothing beyond the download.
