# Chiasma vs Engineering Digest

The clearest difference is iOS requirement: Chiasma at 12.4 against Engineering Digest's 15.1. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Chiasma sells 1 one-off in-app purchase and Engineering Digest sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
