Everyone tells you howyou should feel.We show you.

A free app and a clinically validated cognitive test that measure how your brain actually performs, day after day.

// Why we built it · APP-02

You cannot improve what you cannot measure.

Repeated concussions cut Humphrey Bodington's playing path short. Headaches, light sensitivity, recovery that never quite held, and no clear answer.

During recovery he had fMRI and EEG scans in a Neuro Lab. For the first time he could see his brain measured, not guessed at. That became CONKA: an app that gives everyone the same ability to see it. A number you can watch move.

// The engine · APP-04

Everything in. Patterns out. Down to the millisecond.

Lab-grade analysis of your cognition, built from data your phone already has.

// 01

Everything in.

Sleep, HRV, steps, time outdoors, caffeine, training. Synced automatically from Apple Health on iOS and Android, not logged by hand. And new: screen time, a signal almost nobody has correlated with cognition before. We're watching what it reveals.

Patterns out.

An engine that learns what is true for you. What lifts your score, what drags it, and what CONKA is changing. Not population averages. Your data.

CONKA effect

What shifts on the days you take it: movement, mental fatigue, your score. Measured, not assumed.

Lifting your scores

The habits that reliably lift your number: training days, sleep, time outdoors. Yours will be different. That is the point.

Pulling you down

And what drags it: soreness, low readiness, stress. Clear levers you can pull.

Down to the millisecond.

Every test breaks down into speed, accuracy and consistency, benchmarked against anonymised CONKA users. Spot the dip, tap the day, see the why: caffeine two hours before, no training, a meal 30 minutes out. The kind of forensics you'd otherwise need a lab for.

Millisecond precision

Every response timed to the millisecond. Changes too small to feel, made visible.

Demographic benchmarks

Your scores sit against aggregated, anonymised CONKA users, so you know how you actually fare.

Trends across months

Anything worth improving takes time. Watch the line move across weeks and months, not days.
