# 省心文库 vs 百思文库

省心文库 and 百思文库 are too close to call on the numbers: across 3 compared parameters — price, in-app purchases and iOS requirement among them — neither pulls far enough ahead to decide it. What separates them is feature set and interface, not measurable difference.

Both are free to download. 省心文库 sells 4 in-app purchases, starting at $9.99 per 7 days and 百思文库 sells 3 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.
