Analyse de l'application Coder Calculator pour le 2 octobre

Coder Calculator is a programmer calculator and developer toolkit built for engineers, IT pros, security researchers, and CS students. It replaces five or six scattered single-purpose apps with one focused tool that does the math you actually need at work — base conversions, bitwise operations, hashing, encoding, and AES — all of it running 100% on your device. No accounts. No cloud sync. No data upload. Every calculation, every byte you hash, every string you encrypt stays on the phone. ⚙️ STANDARD & SCIENTIFIC CALCULATOR • Full arithmetic expressions with parentheses and operator precedence • Trigonometry (sin, cos, tan and their inverses) with degree/radian toggle • Logarithms (ln, log10, log2), powers, roots, factorial, modulo • BigDecimal under the hood — no floating-point surprises on long decimals 🔢 PROGRAMMER MODE • Convert between any base from 2 to 36 • Simultaneous HEX / DEC / OCT / BIN view, all synced live • 64-bit binary grid grouped in nibbles for easy reading • Bitwise operators: AND, OR, XOR, NOT, shift left/right, rotate left/right • Bit widths: BYTE (8), WORD (16), DWORD (32), QWORD (64) • Signed / unsigned interpretation, two's complement, ones' complement 🔐 HASH GENERATOR • MD5, SHA-1, SHA-256, SHA-512, CRC32 — computed live as you type • Powered by java.security.MessageDigest (the same crypto libraries banks use) • Results match openssl and any standard hashing tool byte-for-byte 🛡️ AES ENCRYPTION • AES-128 with CBC mode and PKCS5 padding (more modes coming) • Key and IV input with sensible normalization • Encrypt and decrypt in one tap — no shell scripts needed 📝 ENCODING TOOLS • Base64 encode / decode (standard and URL-safe) • URL percent-encode / decode (encodeURIComponent rules) • Hex string ↔ text (UTF-8) • Unicode escape ↔ text 🎨 BUILT FOR DEVELOPERS • Material Design 3 with dynamic color • Light, dark, and system-default themes — flip them in Settings • Monospaced typography that lines up your hex digits • Long-press any result to copy it to the clipboard 🔒 PRIVACY FIRST • All computation happens locally — no network calls for crypto or hashing • No analytics on what you type or compute • One-tap "clear history" in Settings • Optional rewarded ads to support development — entirely opt-in The app is free, supported by occasional ads outside the main workflow. Calculator and tool screens stay clean — no banners obscuring your keys. Built by developers, for developers. Feedback and feature requests are welcome at the contact link inside the app.
