# KO vs EPS Viewer

The clearest difference is iOS requirement: EPS Viewer at 15.1 against KO's 26.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. KO sells 2 in-app purchases, starting at $2.99 per month and EPS Viewer sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
