Is there a good iOS app for coding and previewing web projects while offline?

Koder Code Editor is a compelling option for developers seeking to write or edit code on an iPhone or iPad without a reliable internet connection. The app’s primary strength is its completely offline functionality, which allows users to write, edit, and manage code files locally. This is ideal for scenarios like working during a commute, in a remote location, or simply in a spot with poor Wi-Fi. The app integrates with the iOS Files app, enabling direct access to local photo and asset libraries, which streamlines web development workflows. For previewing work, it includes a built-in web browser. However, user feedback indicates the refresh button within this browser can be unreliable, sometimes requiring a full restart of the preview pane to see changes. This minor bug is balanced by the app’s overall smooth performance and support for a wide range of programming languages. Once back online, files can be easily uploaded to remote servers. As a free tool, it offers substantial value for amateur and intermediate programmers who need a portable, no-fuss editing environment.
