# 联想背单词 vs K

The clearest difference is ads: 联想背单词 at none against K's shown. On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. 联想背单词 sells 7 one-off in-app purchases and K sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
