# Electrical Engineering vs 阴符经：天机秘卷

The clearest difference is ads: 阴符经：天机秘卷 at none against Electrical Engineering's shown. 阴符经：天机秘卷 also leads on iOS requirement (15.1 vs 17.6). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Electrical Engineering sells 2 one-off in-app purchases and 阴符经：天机秘卷 sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
