# 百思文库 vs ViralSaver

The clearest difference is iOS requirement: 百思文库 at 12.0 against ViralSaver's 16.6. On price and in-app purchases there is nothing between them.

Both are free to download. 百思文库 sells 3 in-app purchases, starting at $2.99 per 7 days and ViralSaver sells 2 in-app purchases, starting at $5.99 per month. Whichever you choose, the download price is not the number that matters.
