Cognitive fitness, measured
The Whoop for your brain.
Fathi pairs EEG-sensing earbuds with digital-behavior analytics to score your attention, focus recovery, and stimulation baseline — and train them back.
Named for my grandfather Fathi — 94 years old and cognitively sharp. Proof that a protected mind lasts a lifetime.
We measure everything about our bodies. Nothing about our minds.
47 sec
average attention on a single screen before switching, down from 2.5 minutes in 2004 (Dr. Gloria Mark, UC Irvine)
23 min
average time to fully refocus after an interruption (Mark et al., UC Irvine)
'Cognitive debt'
MIT Media Lab (2025): AI-assisted writers showed the weakest neural connectivity, measured with EEG
A closed loop: measure → understand → train.
Capture
Phone software reads your digital behavior all day; earbuds add EEG ground truth during focus and wind-down.
Fuse
On-device AI cleans the signal and correlates what you did with what it did to your brain.
Score
Three daily scores: Attention Span, Focus Recovery, Stimulation Baseline.
Train
Personalized protocols — focus blocks, stimulus budgets — with measurable before/after proof.
Attention is the wedge. Cognitive longevity is the prize.
Every day of use builds your cognitive baseline. The Lancet Commission (2024) found 45% of dementia cases could be prevented or delayed by addressing modifiable risk factors — but prevention requires measurement, and nothing measures the brain daily. Fathi is the missing layer.
