Brain health, measured daily
Totem is a small device for your nightstand. Three quiet minutes each morning, and it tracks how your mind is doing over time, like a fitness tracker for your brain.
A dedicated device, not another phone app. It sits on your nightstand and glows.
Three quiet minutes each morning: breathe with it, then a few simple taps. No screens.
A private record of your brain health that grows for years, so a slow change surfaces as a trend long before you'd feel it.
It measures. It never grades you. There's no daily score to chase.
A daily ritual object
for your mind.
It glows. You place your hands on it. It breathes with you, and while you settle, it listens.
You track your sleep. Your heart. Your VO₂ max.
But the organ that makes you you flies completely blind.
Decline begins silently in your 30s. Twenty years before the first symptom.
"Johnson measures every organ. Huberman protocols every system. Neither can tell you how their brain is actually doing today. That's the gap."The Muninn Cognition thesis
When it flashes copper, press it, fast as you can. No score. No grade. Just the gap between seeing and doing.
Seeing → deciding → doing, collapsed into milliseconds. The substrate everything else rides on.
Suppressing the response a world of notifications wants you to make.
The mental scratchpad, the first thing a short night takes from you.
The price your brain pays every time you alt-tab, and the first muscle modern work wears down.
The full executive triad (inhibition · updating · shifting) on the processing-speed substrate.
The trendline plots a single composite index, normalized against your own rolling baseline: an intraindividual z-score, never population norms. Six sub-scores feed it:
The sub-scores are always yours to open. The default view is always the direction, not the digits.
An heirloom for a generation that needs anchors.

"I watched my grandfather fade into Alzheimer's. Cognitive decline isn't a cliff. It's a slope that begins decades before anyone names it, with no baseline to measure against. Your 30s and 40s are the window. We're building the instrument for it."
