App大学 (旧Flutter大学) vs Binary Hex Number Converter

スマホアプリ開発に特化した学習コミュニティ「App大学」の公式アプリです！ ライセンス同意書 https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

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.
