hexJapality vs ByteSniffer

hexJapality is a mobile hex viewer and binary inspection toolbox for developers, students, and technical users who need to explore files at the byte level. Open local files on your device, move through offsets, and view bytes in HEX, DEC, OCT, or BIN with printable ASCII alongside the raw data. Select any byte to inspect common interpretations including unsigned integers, signed integers, floats, binary, hex, and ASCII. Built-in tools help you understand file structure faster: • Edit individual bytes with undo and redo before saving • Search for text or exact hex byte patterns • View file size, MD5, and SHA-256 • Detect common formats such as PNG, JPEG, PDF, ZIP, ELF, and GIF • Explore entropy and byte distribution maps • Scan for readable strings and jump to offsets • Add bookmarks for important locations • Compare two files with Binary Diff • Export bytes as a C array, Rust array, hex string, or Base64 Privacy: Files you open are processed on your device.
