Runestone Text Editor vs Hex Editor

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 github.com/simonbs/runestone

"Hex Editor is built around precise hexadecimal editing rather than treating file inspection as an afterthought. Core search language includes hex editor, binary editor, hexadecimal editor, binary file, byte editor. Open a file, move through its byte data, search for a value or text sequence, copy what you need, change the required bytes, and save the result. Use the editor when a normal document viewer cannot show the actual bytes stored inside a file. Byte-level searching helps locate known signatures, strings, offsets, markers, or values without manually scanning an entire file. File Info gives you a quick view of basic file details before you begin deeper inspection. File Type Detector helps identify a file from its content when the extension is missing, unusual, or not enough for your workflow. Metadata Inspector provides another layer of context for understanding information carried by a file. Bit Inspector lets you move below the byte level and examine individual bits when binary representation matters. Hex Calculator is useful for hexadecimal arithmetic, offsets, values, and other low-level calculations. Byte Converter provides quick conversions when you need to move between byte-oriented values while analysing data. Text-Hex connects readable text with hexadecimal representation so you can investigate how characters appear in raw data. Encoding Converter helps you inspect data across supported character encodings instead of guessing how a byte sequence should be interpreted. Base64 Converter gives you a dedicated way to encode or decode Base64 data during technical investigations. String Scanner helps reveal readable text embedded inside binary content and can speed up an initial inspection. Hash Generator provides hashes for data checks and technical workflows where a repeatable fingerprint is useful. Checksum Tool supports checksum-oriented verification when you need to compare calculated values with expected data. Compare Files helps you identify differences between two files instead of relying on visual inspection alone. Entropy Analyzer provides a statistical view that can help you recognise changes in data characteristics across binary content. Byte Statistics summarises byte-level patterns so you can understand data distribution without reading every value individually. These tools work together for reverse engineering workflows, debugging, file inspection, data recovery preparation, protocol investigation, and general developer work. Hex Editor can also be useful when you need to confirm a small binary change, investigate an unknown file, or validate data before moving it elsewhere. Import your file into the toolkit, inspect the relevant region, make only the required edit, then save the resulting file for your next step. The app keeps common binary utilities close to the editor so you can move from editing to analysis without changing applications. Search, copy, inspect, convert, compare, calculate, and analyse from one mobile workspace. Free access provides limited usage, while Pro is designed for users who need unlimited Hex editing. Hex Editor does not replace specialised forensic or reverse-engineering suites; it provides a practical mobile toolkit for everyday hexadecimal and binary work. Use the editor for focused byte changes and use the supporting tools when the surrounding data needs more context. Whether you are checking a binary structure, looking for a string, comparing versions, or validating a checksum, the workflow stays centred on the file data itself. The interface is designed for direct access to low-level information without requiring a separate desktop utility for every small inspection task. Use it when a binary file needs a small, deliberate change rather than a complete rewrite. Inspect hexadecimal offsets when you need to understand where a value occurs in a file.
