# QuickCalc vs FocusLens

The clearest difference is device support: QuickCalc at 3 against FocusLens's 1. QuickCalc also leads on iOS requirement (12.0 vs 16.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. QuickCalc sells 1 one-off in-app purchase and FocusLens sells 2 in-app purchases, starting at $8.99 per month. Whichever you choose, the download price is not the number that matters.
