# 数字开封 vs 美达

The clearest difference is in-app purchases: 美达 at none against 数字开封's 10. 美达 also leads on iOS requirement (9.0 vs 13.0). On price, ads and device support there is nothing between them.

Both are free to download. 数字开封 sells 10 one-off in-app purchases. 美达 asks for nothing beyond the download.
