# Aphelion vs 4Mind Block

The clearest difference is iOS requirement: 4Mind Block at 13.0 against Aphelion's 16.0. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Aphelion sells 1 one-off in-app purchase and 4Mind Block sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
