HTML Editor is a mobile-optimized application that simplifies HTML coding and previewing directly on iOS devices. It stands out for its split-screen functionality, allowing users to write code in one pane while viewing the live-rendered output in another. This feature is particularly useful for web developers, students, or hobbyists who need to test changes on the fly, such as tweaking a website layout during a commute or debugging code while away from a desktop. The app includes syntax highlighting and auto-indentation to reduce errors, and its file management system supports organizing multiple projects. However, the free version displays persistent popup ads promoting a $4-per-week pro subscription, which some users find disruptive for casual use. Reviews indicate that while the cost may not suit occasional coders, the app's reliability and intuitive design make it a practical choice for professionals who frequently work on mobile. Minor interface quirks, like occasional lag with larger files, are noted but don't significantly hinder the experience. Overall, HTML Editor balances functionality with accessibility for on-the-go coding needs.
