# ReadSync vs PDF SuperApp

The clearest difference is iOS requirement: PDF SuperApp at 13.0 against ReadSync's 18.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. ReadSync sells 1 one-off in-app purchase and PDF SuperApp sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
