Cognitive Performance Tracking - Measure Your Brain
The missing metric.
For your mind.
5 minutes a day. Your own personal baseline.
The Problem
Standard tests compare you to strangers.
Population averages miss the signal. Your cognitive performance fluctuates daily. A "normal" score might be your worst day. Or your best.
We compare you to you.
The Protocol
5 tests. 5 minutes. Clinical precision.
Each assessment measures a distinct cognitive domain. Together, they paint a complete picture.
Reaction Time
30sBasic alertness and neural speed
Vigilance
90sSustained attention over time
Working Memory
45sHold and manipulate information
Inhibition
60sCognitive control under conflict
Processing Speed
60sSymbol-digit substitution
The Outcome
Stop guessing. Start knowing.
Most people have no idea if their supplements work or what their cognition is doing. Thalen changes that.
"Does magnesium even work?"
"Am I sharp today or just tired?"
"When should I do deep work?"
+12% focus on magnesium days
Down 8% from your baseline
You peak around 10am
The Science
Grounded in peer-reviewed research.
Individual baselines vary up to 40% from population norms1, and daily fluctuations often exceed the effect size of most interventions2. Personal tracking detects meaningful change with 3× greater sensitivity3.
