# ListenPDF vs Chapter One 1

The clearest difference is iOS requirement: ListenPDF at 16.0 against Chapter One 1's 18.2. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. ListenPDF sells 1 one-off in-app purchase and Chapter One 1 sells 1 in-app purchase, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
