I built a new app and I don't know how I feel about it (philna.sh)

A developer has successfully created a time zone conversion app using OpenAI's Codex, marking a significant milestone in the evolution of AI-assisted coding. The app aims to streamline the process of comparing time zones for globally distributed teams, addressing shortcomings found in existing applications like Savvy Time and World Time Buddy, such as excessive advertisements and poor mobile functionality. Leveraging modern web APIs, Codex helped craft a performance-oriented application that operates offline and maintains a user-friendly experience, which includes features like real-time updates and URL-based state management. This development is noteworthy for the AI/ML community as it exemplifies the potential of AI coding assistants in application development, illustrating a shift from simple code completion tools to collaborative coding partners. The developer's experience underscores the importance of expertise in informing AI workflows, as they navigated Codex's initial outputs to refine the app and improve its functionality. The project not only resulted in a practical application that the developer enjoys but also sparked reflections on the implications of AI in coding, including the blend of human creativity with machine efficiency in software development.
