# Touch Trigonometry vs Omega Studio

The clearest difference is iOS requirement: Touch Trigonometry at 15.1 against Omega Studio's 18.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Touch Trigonometry sells 1 one-off in-app purchase and Omega Studio sells 2 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.
