This blog exists because we hate vague health advice.

"Get more sleep." "Try this supplement." "Optimize your morning routine." None of it comes with data. None of it tells you if it actually worked for you.

What We'll Cover

Research breakdowns. The actual science behind cognitive tests. Why we chose PVT, N-Back, Stroop, and DSST. What the studies show. What they don't.

Practical guides. How to run proper n-of-1 experiments. How to interpret your scores. How to separate signal from noise.

Product updates. New features. Methodology changes. The reasoning behind our decisions.

Why Thalen Exists

Wearables measure recovery. High HRV, good sleep score, green ring. But none of that guarantees sharp thinking.

We built Thalen to measure cognition directly. Reaction time. Working memory. Attention. Processing speed. Against your personal baseline, not population averages.

The blog extends that mission. We share what we're building, why, and how.
