A backend developer's journey building WSL-UI revealed that UI polish consumes more time than feature development. The author spent 50% of effort on visual consistency, state management, and edge cases—far exceeding the clean contracts of backend work.

This experience highlighted the subjective nature of UI work, where pixel-perfect alignment and responsive design across screen sizes matter. The developer created state machines to track UI element visibility, a concept unnecessary for REST APIs.

After publishing to the Microsoft Store, the author implemented Aptabase for privacy-first analytics. The tool collects minimal data—OS version, app version, and custom events—with no user IDs or personal information. Analytics are opt-out by default, respecting user privacy.

The data revealed which features are actually used, helping prioritize polish efforts. For solo developers, this balance of insight and ethics provides a model for informed development without betraying user trust.
