# Aix vs SkillForge

The clearest difference is in-app purchases: Aix at none against SkillForge's 1. Aix also leads on iOS requirement (15.1 vs 18.0). SkillForge's advantage is device support (4 vs 2). On price and ads there is nothing between them.

Both are free to download. SkillForge sells 1 one-off in-app purchase. Aix asks for nothing beyond the download.
