Measure your mind.
Then train it.

Nine subtests. Six abilities. A score that shows its margin of error.

Free to take. The full six-index report is a subscription — and the score itself is always yours.

Our methods are grounded in decades of peer-reviewed cognitive-science research

What you'll train

One app for every part of your thinking

Fluid intelligence

Reason through novel problems — the raw horsepower your IQ is built on.

Math exercises

Mental arithmetic, estimation and number sense, trained under pressure.

Memory boost

Working and spatial memory drills that expand how much you can hold.

Focus boost

Inhibition and attention control, so distractions lose their grip.

Speed boost

Sharpen reaction time and processing speed for quicker thinking.

Data tracking

Every session tracked — watch each skill climb over the weeks.

Train the skills behind better cognition

Step one

Hold the cue

Keep the target in mind while distractions compete for your attention.

Step two

Decide under pressure

Make quick, accurate judgments when the task pushes on your control.

Step three

Adapt as you improve

Difficulty adjusts to your performance so the challenge stays effective.

Built on real cognitive-training tasks

Cognitive Control Training

Inhibition and attention drills that build the self-regulation behind steadier focus, calmer thinking, and better habits.

Relational Reasoning Training

Structured reasoning that strengthens problem solving, reading comprehension, and the ability to connect ideas under pressure.

Cogni is a training and self-tracking tool, not a medical or diagnostic service. It isn't a replacement for therapy or professional care.

Questions

How long does it take to see changes?

It varies by person and consistency. Most people train a few minutes most days; the point is a sustainable habit, not a single session.

Is this a replacement for therapy or medical care?

No. Cogni is a training and self-tracking tool. If you're dealing with a health concern, talk to a qualified professional.

What if I miss days?

Nothing breaks. Your progress is saved to your account — pick up where you left off whenever you're ready.

Is it suitable for students and younger users?

The exercises are designed to be broadly accessible. Younger users should have a parent or guardian involved.

Exercises

Standalone Exercises

Memory

N-Back

Train position, color, shape, and audio matching with adaptive N-back sessions.

Focus

Relational Reasoning (RRT)

Spatial premise training for abstract logic and mental model building.

Focus

Cognitive Control Training (CCT)

Adaptive serial addition for focus, inhibition, and mental endurance.

Focus

Inhibitory Control (ICT)

Respond quickly to go cues, then withhold your response when a stop signal appears.

Memory

Grid Memory

A pattern of tiles flashes on the grid — reproduce it from memory. It grows each level.

Memory

Sequence Memory

Numbers appear across the board, then vanish — tap the squares in order from memory.

Memory

Number Recall

A number flashes, then you type it back. One more digit is added every round.

Verbal

Word Memory

Words appear one by one — mark each as new or already seen. The list keeps growing.

Focus

Reaction Time

Wait for the screen to turn green, then tap as fast as you can. Five trials, averaged.

Math

Mental Math

Ten quick questions — arithmetic, estimation, and odd-one-out. No calculator; it ramps up as you go.

Verbal

Spot the Fallacy

Read a short everyday argument and name what's wrong with it — or spot when it's actually valid. Adapts as you sharpen.

Focus

Patience

Hold one word in mind while others drift slowly past. Press only when yours returns. A long, calm session that rewards the quiet hold.

Training Focus

Cogni IQ Test

Take the test

Nine short subtests across six abilities, taken in any order. Each is a single sitting — you can stop early, but you can't return to it.

Pick a subtest

Take them in any order. Each is one sitting — stop early if you need to, but you can't return to it.

Scores are estimates from provisional item data, for personal tracking only — this is not a clinically validated intelligence test.

Start a new test?

This clears the subtests you have already finished in this attempt and starts a fresh one. Reports you have already earned are kept.

Subtest

One sitting. You can stop early and whatever you've answered is scored — but you can't pause it, come back to it, or retake it in this attempt.

No external aids — no calculator, notes, search or AI.
