# Calculator² vs Focus Timer

The clearest difference is iOS requirement: Calculator² at 9.0 against Focus Timer's 16.4. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Calculator² sells 3 one-off in-app purchases and Focus Timer sells 6 in-app purchases, starting at $14.99 per month. Whichever you choose, the download price is not the number that matters.
