# QuadraFocus vs 카리투두

The clearest difference is iOS requirement: 카리투두 at 15.0 against QuadraFocus's 26.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. QuadraFocus sells 2 in-app purchases, starting at $2.99 per month and 카리투두 sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
