Here's what vibe coding actually looked like in practice. What AI handled well ~70% of boilerplate on first pass navigation, state management, notification scheduling. I described the architecture in plain language, got working code back. Content generation, App Store copy drafts, edge case surfacing. That part felt like flow. Where the vibe broke: judgment calls AI suggested a standard onboarding. Generic, functional, wrong. Good UX requires knowing why someone opens an affirmation app at 7am what emotional state they're in, what friction kills the habit before it forms. Scrapped it. Built from scratch. Same with notifications.
