# PDF Master vs Audio Editor

The clearest difference is iOS requirement: PDF Master at 11.0 against Audio Editor's 13.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. PDF Master sells 13 in-app purchases, starting at $2.99 per 7 days and Audio Editor sells 3 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.
