# PDF Reader vs 实用英语900句系列

The clearest difference is iOS requirement: 实用英语900句系列 at 10.0 against PDF Reader's 12.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. PDF Reader sells 5 one-off in-app purchases and 实用英语900句系列 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
