# MobilEM vs DDx

The clearest difference is chart position: MobilEM at #38 against DDx's unranked. MobilEM also leads on iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. MobilEM sells 10 in-app purchases, starting at $1.99 per year and DDx sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
