# Kaliper vs Key Library

The clearest difference is ads: Key Library at none against Kaliper's shown. Kaliper's advantage is iOS requirement (14.0 vs 18.6). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Kaliper sells 1 one-off in-app purchase and Key Library sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
