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. Premium features are unlocked with a one-time in-app purchase that’s currently priced at $9.99 USD. Pricing may vary from country to country. Runestone was built on the open-source framework with the same name. Find more information on the Runestone framework at

  • Can we get Fountain formatting?

    By Carl in Oakland
    What a wonderful lightweight app. I use it to code and write mark down with the inspiration hits. While not specifically a coding language, I would love to see the mark down language "fountain" supported.
  • Please add an option to hide the symbol bar

    By HackedPotato
    Runestone is absolutely amazing for what it does. I just wish the symbol bar could be toggled with a setting on demand.

  • Just get it already

    By Aviris
    If you’re looking, you know what it is and I’ll tell you it is worth it. Even without premium it’s a great text/markdown editor. If you use it even a couple times a week the premium update is worth it and reasonable for what you get (my opinion of course).
  • Extremely high quality app

    By Jason Sewell
    Until BBEdit is published for iOS, Runestone is my editor. It is very polished, intuitive, and powerful. It makes editing source code far less painful on an iPhone or iPad. In fact, with an external keyboard paired, it’s actually quite pleasant. Everyone should have a good text editor in their toolbox. As far as I’ve seen, Runestone is the benchmark.
  • Pleasure To Use

    By Alscwh
    It is so nice to open and use an application produced by someone who truly thought about its use and function. Runestone is a well-planned, well-designed app. It's a pleasure to use because it was designed that way. Great purchase.
