NeuroMetric App

The NeuroMetric App — Like a Fitbit for Your Brain.

Your Personal Mental Clarity Tracker

Know when your brain is sharp, and when it's running on fumes.

We all have foggy days and razor-sharp days. Most of the time we just feel the difference and guess. The NeuroMetric app turns that feeling into a real number you can see, track, and improve.

In about 3 minutes, a simple tap-the-light test measures how fast and how steadily your brain is firing — then hands you a clear snapshot of your mental clarity right now.

Using our proprietary AI-powered algorithms, the NeuroMetric app delivers valuable insights into your focus, mental fatigue, and cognitive flexibility. It's the first digital biomarker for neurocognitive longevity.

Many things can interfere with your ability to process information and respond quickly — not enough sleep, overtraining, too much stress. Meanwhile, plenty of companies sell products that promise increased focus and reduced mental fatigue.

But do these products actually work? And how do the protocols you want to try really affect you?

Now the answer is in your hands. The NeuroMetric app doesn't just give you a daily Cognitive Performance Score — it helps you pinpoint which parts of your daily life, self-care routines, and supplements raise or lower your cognitive performance.

This app is designed for people looking to maximize their cognitive capacity — and to recognize the cognitive slowing that can come with overwork, mental fatigue, long COVID, and sleep deprivation.

It's the first handheld app that assesses and monitors your daily cognitive readiness.

What you'll see after every test

• Performance Score (0–100) — one easy number that sums up how sharp you are today
• Cognitive Speed — how quickly your brain reacts, in reactions per second
• Reaction Time Stats — your fastest, average, and slowest responses at a glance
• Fatigue Factor — false starts and lapses that reveal hidden mental tiredness
• Focus, Resilience & Flexibility — plain-language sliders showing whether you're locked in or easily distracted
• Reaction Time Curve — a simple graph showing if your focus held steady or faded as you got tired

Why measure your mental clarity?

• Catch brain fog early — see a dip before it wrecks your workday
• Prove what actually works — test before and after coffee, a workout, a nap, a supplement, or a light session and watch the numbers move
• Understand your fatigue — lapses and slow reactions often show up before you consciously feel drained
• Track progress over time — turn "I think I feel better" into "my score went up 12 points"
• Optimize your day — learn when your brain peaks so you can schedule your hardest work for then

How it works

1. Tap Start and take the quick reaction-time test
2. React the instant the light changes — that's it
3. Get your full clarity report in seconds
4. Tag it as a Pre or Post session to compare before-and-after

Who it's for

• High performers who want an edge on focus and sharpness
• Anyone battling brain fog, fatigue, or foggy afternoons
• People testing sleep, supplements, light therapy, or recovery routines
• Curious minds who love tracking their own data

Simple to take. Easy to read. Backed by a reaction-time method used in real cognitive research.
