LinkedIn Post — the Proof Floor

Don't explain the app. Prove it. Copy-ready.

I was struggling to explain what my app can do. So I built a floor that doesn't explain — it proves. New in The Human Brain App: /proof — one public page where you don't read about the app, you USE it. Three demos, all running live in your browser right now, no account, nothing saved: 🧠 The Stroop Test — a real cognitive measure. 8 rounds, your reaction time in milliseconds. When the word "RED" is written in green ink, your brain pays a measurable cost. The app measures YOUR cost, live. 🎨 The Color Harmony Engine — drag one slider, get four professionally-correct palettes (complementary, analogous, triadic, split-comp). Real wheel math, recomputing instantly as you move. 🌕 Any Night's Moon — pick any date — a birthday, a night you remember — and see the moon that hung there: phase, illumination %, age in days. Standard astronomy formula, computed the instant you pick. That's the whole pitch in 60 seconds. Not screenshots. Not "coming soon." Not a waitlist. The actual math, running on your machine, before your coffee cools. No-fibs corner, because this app never fibs: the Stroop test is a study toy, not a clinical assessment. The palettes are exact HSL rotation, not perceptual color science. The moon is accurate to about a day, not an ephemeris. And every demo's limits are printed on the page — right under the demo itself. Most software asks you to believe. This one asks for 60 seconds.

Run the demos before you post Re-check the claims against the page

Claim check (no-fibs)

  • "Running live right now, no account" — true: /proof is a public route; all three demos are client-side math with zero network calls.
  • "Nothing saved" — true: no entity writes, no analytics on the demos; results render on screen only.
  • The limitations quoted (study toy, HSL rotation, ~1-day moon accuracy) appear verbatim in the page's own no-fibs banner.
  • "Not screenshots, not a waitlist" — the demos are fully interactive on the page; the post doesn't inflate them beyond that.
