CosNFX is a Wear OS app that fires costume sound effects and visuals when you move. Thirty character kits are free and work offline; Pro is a one-time purchase for custom content, timelines and connected props.
It's made by the CosNFX workshop — creative technology and interactive systems, and the maker of a small family of tools for real workshops: Bead Bench (eleven bead crafts), Fiber Bench (nine weaving and stitching crafts), Cellar Math (fermenting, brewing, chocolate and dye), Planetaria (the live Earth on a desk globe) and CosNFX Play, this site's workshop half.
The craft knowledge stays free: build sheets, guides, video from real makers, and the games and demos that teach the moves.
