# 地下道 vs GravityJump

The clearest difference is in-app purchases: 地下道 at none against GravityJump's 1. 地下道 also leads on ads (none vs shown) and iOS requirement (13.0 vs 17.0). On price and device support there is nothing between them.

Both are free to download. GravityJump sells 1 one-off in-app purchase. 地下道 asks for nothing beyond the download.
