"Vibecode" helps you turn an app idea into a structured app project. The app guides you through refining your idea into a clear specification before building. This includes defining features, screens, user flows, and edge cases. Refining the specification first helps reduce rework during later updates. You can start with a brief idea or a detailed draft. "Vibecode - mobile app builder" converts the refined specification into a runnable project that you can preview, update, and share. Changes are applied through guided updates rather than rebuilding the project from the beginning. Features: - App specification refinement before building - Project generation based on a structured specification - Guided updates to existing projects - Runnable previews and sharing - Project history and continuation - Version management and rollback - Install app to home screen Account Requirement: - An account is required to save projects and access project history.
