# HTML Viewer Pro vs MathLib

The clearest difference is ads: MathLib at none against HTML Viewer Pro's shown. HTML Viewer Pro's advantage is device support (3 vs 1) and iOS requirement (12.0 vs 17.0). On price and in-app purchases there is nothing between them.

Both are free to download. HTML Viewer Pro sells 2 in-app purchases, starting at $1.99 per month and MathLib sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
