## What is NUMEN?

"Not solving math — the moment you start to feel it."

NUMEN is not a problem-set app.
It's an app for everyone who once gave up on math — and wants to recover the sense of it.

■ A different approach

Other math apps:
Definition → Formula → Practice → Wrong answer

NUMEN:
Experience → Pattern → Intuition → Definition

You touch with your finger. You drag a slider. You watch values change. Each fraction slice, each function curve, each direction of a negative number — every concept comes alive as moving math, not memorized math.

■ Who is this for?

· Middle and high school students who lost the thread
· People burned out on classroom-style explanations
· Adults who want to understand investing, statistics, or AI
· Anyone who wants to feel "I wasn't bad at math — the connections were just broken"

■ What's inside

· Interactive lessons you actually touch
  33 lessons across 10 phases — sense, relations, change, chance, shape, cycles, limit, slope, accumulation, direction
· Intuition first, definition later
  See the phenomenon, find the pattern, then meet the formal name
· 5–10 minute daily sessions
  Light enough to keep, deep enough to transform
· Daily streaks
  A little, every day — that's how sense rebuilds
· Four languages
  Korean · English · Japanese · Simplified Chinese — every lesson body translated
· iPhone · iPad universal
· Fully offline
  No ads. No tracking. No data collection. No internet calls.

■ Why NUMEN?

You weren't bad at math.
Only the connections between concepts were broken.
NUMEN was designed — by hand, with care — to reconnect them.

"Oh — I wasn't dumb.
The connections were just broken."

That moment is what NUMEN is built for.

■ Privacy by design

NUMEN collects zero personal information. All progress is stored only on your device. No analytics, no advertising SDKs, no external APIs.

■ Pricing

· The app itself — free to download
· Phase 1–3 (12 lessons, ≈ 60 min of content) — free
· Phase 4–10 (21 lessons) — single one-time in-app purchase, unlocks forever. No ads, no subscription, no renewal.

■ Coming next

· More lessons within Phase 5–10
· Personal review / notes screen

Begin today.
Mathematical sense is not memorized — it is recovered.
