## What is Learn Binary?

Finally understand binary and hex — by doing, not memorising.

Learn Binary turns number-base conversion into fast, satisfying drills. See a number, build the answer on a tappable bit row or a clean keypad, and get an instant verdict with the place-value breakdown behind it. It's built around how you actually learn: a level climb, an ~80% mastery gate, and a three-minute daily habit.

WHAT'S INSIDE
- The drill — convert decimal ⇄ binary ⇄ hex, both directions. Tap the bits or type the digits, confirm, and see exactly why the answer is what it is.
- The nibble block — the standout: see how 0x61 = 0110 0001 = 97, with hex sat over colour-coded 4-bit nibbles. This is the trick that makes hex click.
- A level climb — one level per bit, from the first switch up to the full byte (the 256 Club) and beyond. Clear a level test to unlock the next.
- Two's-complement — read and write signed bytes, with the sign-bit reveal.
- Bitwise ops — AND, OR and XOR, worked one column at a time.
- Byte Speed Run — an optional 60-second timed challenge once you've earned it.
- Daily goal + streak — a gentle habit, with a streak freeze so one missed day doesn't wipe your progress.
- Explore — scrub a number and watch decimal, binary and hex move together.

BUILT RIGHT
- Fully offline — no account, no sign-up, no tracking required.
- A clean, friendly light design in apricot and teal.
