This is for building iOS, Mac, and web apps that actually feel native and human, not like they came from a template generator. It's opinionated about motion design, pushing you toward spring physics over linear animations and warning against what it calls "generic card syndrome" and "rainbow vomit." Works with SwiftUI, React, and Vue, plus it hooks into Stability AI for mockups and 21st.dev for component patterns. The whole thing is built around avoiding that flat, soulless aesthetic that screams AI-generated. If you're prototyping an app and care about the animation details and microinteractions that make users actually enjoy the experience, this gives you specific guidance on spring damping values, timing windows, and when to break the grid intentionally.
