# DoCube vs 7Exp

The clearest difference is in-app purchases: 7Exp at none against DoCube's 1. 7Exp also leads on iOS requirement (15.6 vs 17.0). DoCube's advantage is device support. On price there is nothing between them.

Both are free to download. DoCube sells 1 one-off in-app purchase. 7Exp asks for nothing beyond the download.
