# Clefs vs Kinor

The clearest difference is iOS requirement: Kinor at 15.0 against Clefs's 18.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Clefs sells 1 one-off in-app purchase and Kinor sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
