# Ad vs STL Workshop

The clearest difference is in-app purchases: STL Workshop at none against Ad's 1. On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. Ad sells 1 one-off in-app purchase. STL Workshop asks for nothing beyond the download.
