Geekulator for Geeks vs hexJapality

Sometimes geeks need a special type of calculator to do special geek stuff. Geekulator is that calculator. It handles the most common integral base conversions as well as all those everyday bit-wise operations we're constantly goofing around with. It even does OSType (4-char code) conversions, although those aren't as common these days as they once were in Mac development. The style and layout is based on one of the most gorgeous calculators of its day, the Unisonic CB-14: Its clean style impressive, its buttons and switch sure and solid. Features: •Automatic display of binary, decimal, hex, and OSType. •Input switchable between binary, decimal, hex, and OSType. •Tappable binary bits. (Good luck hitting the right one with normal sized human fingers!) •Sign switch for choosing signed or unsigned integers in the decimal display. •The 4 common math operators, plus mod (%), a +/- button, and bitwise operators (and, or, xor, and not). •Bit shifting operators, both single shift or valued shift. •Choosable LED display colors. •Choosable LED fonts.

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. We do not upload your file contents to our servers. Free version: The app is free to download and may display ads.
