- 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.
