Smart multi-tools, now for body & mind

Train your mind.
Understand your health.

CogniTrack Pro turns a simple daily routine — cognitive exercises, Apple Watch signals, and Apple Health data — into clear, private insight on your iPhone. Built by a bioinformatician who got tired of guessing.

Why it matters now

In a noisy world, clear thinking is your edge.

Endless feeds, constant pings, more inputs than any mind was built to hold. Focus frays, recall slips, and good decisions get harder. CogniTrack Pro is the daily reset that keeps your attention sharp — and the quiet proof that it's actually working.

Beat the brain fog

Always-on inputs fragment attention and leave you foggy. A few minutes of structured routine protects your focus before overload sets in.

Become a cognitive athlete

As AI gets smarter, the advantage shifts to people who think clearly and prompt deliberately. A sharper mind gets far more out of every model.

Train focus & creativity

Attention, working memory and processing speed respond to consistent practice — the same way your body responds to training.

Invest in healthy aging

Mind and body age together. Small signals, tracked over years, are where longevity is actually built — quietly, and on your own terms.

The same DRFRIEDELS principle

One useful tool. Many everyday problems solved.

DRFRIEDELS began with compact physical multi-tools for real-life repairs, travel, and small daily tasks — the right tool, always in your pocket. CogniTrack Pro carries the same idea into software: one focused tool that quietly keeps your mind, body, and recovery on track, instead of five apps that each track a slice.

Why I built it

I build smart tools for a living. This time I built one for myself.

I started out in bioinformatics — teaching machines to find the signal in messy biological data. From there the work carried me through a lot of different fields, but the mission never really changed: build smart tools, and push what AI can actually do for the people using it.

At some point that mission turned personal. I care about longevity — not the magic-pill kind, but the boring, durable kind. And the more research I read, the clearer it got: there is no single hack. The compounding returns come from routine — measuring the right signals, training consistently, and learning from your own patterns over time.

But my own data lived in a dozen disconnected places. Sleep here, HRV there, a brain-training app that never talked to any of it. And almost none of it took the obvious step of connecting mind and body — even though recovery, sleep, and stress so visibly shape how sharp you feel.

So I did what I know how to do: I put AI to work surveying the literature, pulled together cognitive tasks with real scientific pedigree — the kind used to measure working memory, attention, and processing speed — and built them into a daily system alongside the health signals an Apple Watch already collects. Morning and evening routines to bookend the day. Plain-language insight instead of raw charts. And one non-negotiable: everything stays on the phone.

CogniTrack Pro is the tool I wanted for myself. If routine is the lever, this is the handle.

A multi-tool for your daily health and cognition — useful, private, and built for real life, not a lab.

Inside the app

Four things, working together — not four apps.

A daily rhythm, a cognitive baseline you can actually improve, the health signals you already wear, and the patterns that connect them.

Guided routines

A morning and evening that take 15 minutes.

Two short, guided routines bookend your day — check-ins, breathing, movement, a cognitive task, and reflection — so consistency becomes the default instead of a daily decision.

  • Morning routine to set a clean baseline
  • Evening routine for recall, reflection, and wind-down
  • Bodyweight workouts and breathing that adapt to you

Cognitive training

Track your mind the way you track your body.

Eight short tasks build a profile across four domains, then turn one-off scores into trends — so you can see whether last night's sleep actually moved your focus today.

Working memory

Hold & manipulate

Keep information in mind and work with it under load.

N-BackDigit Span
Executive function

Focus & inhibit

Filter distraction and hold back the wrong response.

StroopGo/No-Go
Sustained attention

Stay with it

Keep attention steady through monotony.

SARTVigilance
Processing speed

Think quickly

How fast you take in and respond to information.

Symbol-DigitReaction Time

Built on validated paradigms from cognitive science — including the n-back, Stroop, and SART tasks. Scores are personal estimates for tracking your own trends, not clinical assessments.

Apple Health & Apple Watch

Your recovery, in plain language.

CogniTrack Pro reads the signals your Apple Watch already records and translates them into something readable — how recovered you are today, and how that compares to your own normal.

  • HRV, resting heart rate, sleep and activity trends
  • Today vs. your 30-day normal, not generic charts
  • Age-adjusted reference ranges, computed on-device

Patterns & correlations

Find the connections worth testing.

The app looks across your routine, cognitive, and health signals to surface patterns you can turn into small habit experiments — while staying honest about what the data can and can't say.

  • Connect sleep, activity, glucose, screen time and cognition
  • Spot unusual days and the context around them
  • Framed as hypotheses — correlation isn't causation

A closer look

Exactly what you'll see.

No mock-ups — these are real screens from the app.

Private by design

Your health data stays on your iPhone.

CogniTrack Pro was built for personal insight, not data extraction. There are no tracking SDKs, no advertising, and no cloud upload by default.

On-device processing

Cognitive results, routines, and Apple Health insights are stored and processed locally on your device.

No ads or tracking

No third-party analytics, ad tracking, or data selling. The app contains no third-party SDKs.

Transparent limits

A wellness and educational tool. It does not diagnose, treat, cure, or prevent disease.

2

Train deliberately

Complete a short cognitive task and a focused workout that fit a real schedule.

3

Learn from trends

Review recovery, cognition, and the patterns between them — then decide what to change.

FAQ

Clear answers before you download.

Is CogniTrack Pro a medical device?

No. CogniTrack Pro is a wellness and educational app. It does not diagnose, treat, cure, or prevent disease, and it is not a substitute for professional medical advice. Scores and estimates are for personal tracking.

Does it upload my Apple Health data?

No. By default your Apple Health data is processed on your iPhone only and is never sent to the developer or any third party. Apple Health access requires your explicit permission, and you can revoke it at any time in iOS Settings.

Which cognitive tests are included, and are they real?

Eight tasks built on validated paradigms from cognitive science: N-Back and Digit Span (working memory), Stroop and Go/No-Go (executive function), SART and a Vigilance task (sustained attention), and Symbol-Digit and Reaction Time (processing speed). They're adapted for daily self-tracking — research-informed, not clinical instruments.

Why combine cognitive training with Apple Watch data?

Because cognitive performance is shaped by sleep, recovery, stress, activity, and routine. Looking at them together is more useful than either alone — while the app stays cautious about interpretation and frames findings as hypotheses.

Do I need an Apple Watch?

No. The cognitive training and routines work on iPhone alone. An Apple Watch adds the health signals — HRV, heart rate, sleep, activity — that make the recovery and correlation features richer.

How does this connect to DRFRIEDELS multi-tools?

DRFRIEDELS makes focused multi-tools that reduce friction in everyday life. CogniTrack Pro extends that philosophy into software: one tool for the daily routine that keeps your mind and body on track.
