# 百度文库 vs 不背单词

The clearest difference is ads: 不背单词 at none against 百度文库's shown. 不背单词 also leads on review sentiment (95% vs 76%) and rating (4.8 vs 4.6). On price, ratings volume, update cadence and in-app purchases there is nothing between them.

Both are free to download. 百度文库 sells 17 in-app purchases, starting at $1.99 per month and 不背单词 sells 100 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
