# 工程师e家 vs 电气考研

The clearest difference is ads: 电气考研 at none against 工程师e家's shown. On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. 工程师e家 sells 3 one-off in-app purchases and 电气考研 sells 10 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
