Binary Hex Number Converter vs Python Code Cards

Convert any number between binary, octal, decimal, and hex — live, as you type. Every base updates at once, with exact integer math and zero float drift. Most calculators round, guess the bit width, or hide what's actually happening in the bits. This one doesn't. Type a value in any base and read all four representations side by side in clean, monospaced, grouped digits — plus signed and unsigned interpretation, set-bit counts, and the raw bytes, at 8, 16, 32, or 64-bit width. WHAT YOU GET - Every base at once: binary, octal, decimal and hex stay in sync as you type - Any radix from 2 to 36 with a live slider, so odd bases are one tap away - Bit-level truth: signed two's-complement, unsigned, set-bit count and big-endian bytes - Bitwise lab with a tappable bit grid — AND, OR, XOR, NOT and shifts, flipped bit by bit - Developer reference: full ASCII table, powers of two, common masks and a two's-complement explainer - Saved history you can scroll back through and copy any value from PERFECT FOR - Developers reading hex dumps, registers and color values - Embedded and firmware engineers working close to the metal - CS and engineering students learning number bases and bit math - Anyone who needs an exact, no-nonsense radix converter WHY NOT JUST USE A CALCULATOR? A regular calculator drops leading zeros, drifts on large values, and shows one base at a time. BaseConvert keeps exact integer math at a fixed bit width and shows binary, octal, decimal and hex together — so you see the bits, not a rounded guess. PRIVACY Everything runs on-device. No accounts, no ads, no tracking — your numbers never leave your phone. FULL ACCESS The bitwise lab, the full developer reference, and unlimited saved history unlock with Premium — available as a weekly or yearly plan, or a one-time lifetime unlock. Convert between the four core bases free, forever. Type your first value and watch every base light up.

Try the Python code you just found, right on your iPhone or iPad. See why it works by stepping through it. Python Code Cards combines an offline Python 3.14 runtime, an editor, and a step debugger with a notebook for your small code experiments. MADE FOR SMALL EXPERIMENTS • Check a snippet while reading a tutorial • Follow a loop or branch and inspect changing values • Keep useful code with your own notes START WITH CODE THAT ALREADY RUNS Five editable samples include FizzBuzz, Fibonacci, Binary Search, Bubble Sort, and Recursive Factorial. Change a number or condition and compare the results. This is a place to run and explore code, rather than a course or quiz app. PAUSE A LINE. SEE THE VALUES. Set breakpoints from line numbers. Continue, pause, step over, step into, and step out. Inspect variables, watch expressions, the call stack, and output as you debug. KEEP EACH EXPERIMENT AS A CARD Add code cards and notes. Edit, duplicate, collapse, and reorder them. Source, breakpoints, watches, and recent results stay together on your device. WRITE AND CHECK WITH LESS FRICTION Python syntax highlighting and local completion for keywords, built-ins, and symbols in your code. See standard output, exception lines, execution time, and resulting variables. Choose System, Light, or Dark appearance and switch the interface among 10 languages. NO ACCOUNT. NO ADS. NO TRACKING. The core app works without an internet connection. No analytics, tracking, or cloud sync. Cards and settings remain in local app storage and are not automatically sent to the developer. WHAT IS INCLUDED The bundled Python standard library is supported. Installing third-party packages with pip, AI completion, and cloud execution are not supported. Normal execution has a time limit.
