# Calc vs Denoiser

The clearest difference is iOS requirement: Calc at 12.0 against Denoiser's 15.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Calc sells 3 in-app purchases, starting at $5.99 per 7 days and Denoiser sells 2 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.
