# ClearMath vs Touch Trigonometry

The clearest difference is iOS requirement: Touch Trigonometry at 15.1 against ClearMath's 17. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. ClearMath sells 2 in-app purchases, starting at $12.99 per month and Touch Trigonometry sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
