# ChessKnock vs AMSA Chess

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

Both are free to download. ChessKnock sells 1 one-off in-app purchase and AMSA Chess sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
