I used Claude Code to vibe code an Apple Watch app in just 12 hours - instead of 2 months

This article recounts developing an Apple Watch version of a filament management app with Claude Code, highlighting the need to pare down features for the Watch’s constraints, issues encountered when syncing large photo data that strained memory, and the solution to bifurcate data structures so the Watch excluded photos. The author describes an iterative, collaborative workflow with the AI that retained the broader app architecture while achieving a functional Watch app in about 12 hours spread over three weeks.
