# ESP vs QR Code

The clearest difference is iOS requirement: ESP at 16.0 against QR Code's 26.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. ESP sells 1 one-off in-app purchase and QR Code sells 2 in-app purchases, starting at $1.49 per 7 days. Whichever you choose, the download price is not the number that matters.
