A plain text editor with syntax highlighting, line numbers, search and replace, page guide, and much more. It's like TextEdit but more powerful and optimised for iPhone and iPad. Runestone is made by a single person with a love for text editors and a vision of building the most lightweight text editor for iPhone and iPad that still has the core features for editing code. Features: - Syntax highlighting of many languages including HTML, JavaScript, JSON, Markdown, Swift, Python, PHP, YAML, and many more. - Select one of the twelve standard themes including popular themes like Tomorrow, Dracula, Solarized, and One Dark Pro. - Innovative find and replace for searching and modifying text while still viewing your file. - Choose font and font size, including support for custom fonts imported using another third-party app. - Show the line and column the cursor is located on. - Uses the standard document browser for an experience similar to the Files app. - Quickly navigate to a specific line. - Automatically close opening brackets and quotes. - Multiple windows on the iPad. - Format code using Prettier.js. Supported languages include CSS,HTML, JavaScript, JSON, PHP and more. - Choose text encoding between popular encodings like UTF-8, UTF-16, ISO Latin 1, and many more. - Enable or disable autocorrection, autocapitalization, and smart punctuation. - Set default file extension of new files. - Open files in Runestone from the Share Sheet. - Print documents. Premium features: - Choose between eight app icons. - Show line numbers. - Highlight the selected line. - Increase line height and letter spacing. - Disable line wrapping to allow horizontal scrolling. - Show tabs, spaces, and line breaks using a selected symbol. - Enable page guide at a specific column to easily tell when lines are getting too long. - Add vertical and horizontal overscroll. - Remember the selected language per file. - Save file extensions and filenames that should always be treated as plain text files. - Enable soft tabs and choose the width of the tab character. - Specify whether pressing the tab key should insert a tab or indent the line. - Adjust the scaling of Markdown headings and disable highlighting of code blocks in Markdown. Runestone was built on the open-source framework with the same name. Find more information on the Runestone framework at



  • Good solution for missing app.

    I was very surprised that Apple released the Vision Pro without a text editor. All other Apple devices come with one. This app is a simple solution. While I did not need any of the premium features, I purchased the full app to support the developer. Since this will also work on my other devices, I will add it to all of them. I appreciate the developer not making this a subscription like everybody else does. I dislike subscriptions and avoid them like the plague. The developer was kind, I can’t say enough good things about this app. I strongly recommend it.
  • Would be much useful if capable of opening multiple windows

  • Outstanding Editor

    By WhiplashZamboniMan
    If you are a VoiceOver user like I am and on iOS 17.4.1, there is one small problem when punctuation is set to anything but all under VoiceOver, verbosity. When walking through a text file line by line, VoiceOver fails to include the last character of every line whether or not the last character is punctuation. Setting verbosity for punctuation to all correctly identifies every character on the line. This editor is quick! A few of the others I've tested that are supposed to work with VoiceOver are so slow they are completely useless. I'm using this editor to write LaTeX documents and it works very well.

  • Excellent visionOS Text Editor

    By A Reviewer Name
    A button/toggle for read-only would be appreciated as my usecase (code review) doesn’t necessitate editing features but the ability to disable edits would be useful to prevent accidental changes.
  • No way to open folders?

    Great to have this on Apple Vision Pro. Thank you!
  • Super clean and lean

    Really nicely implemented. Cursor control actually works as opposed to many other early vision apps.
