Eurêka started from a simple product question: how can unfinished thoughts stay spatial, tactile and useful before they are ready to become documents? I’m taking it from interaction model to working iOS software.
The problem behind the surface.
Selection, writing, dragging, resizing and canvas navigation all compete for the same small touch surface. Every gesture has to reveal intent without making the canvas feel like a form or a tool palette.
I define the product direction, interaction rules, interface system and roadmap, then test those choices in SwiftUI, Simulator and the Eurêka Lite web demo.
