Cognitive fitness for the dopamine age

Want the hit? Earn it first.

Every time you reach for a quick dopamine fix, Cognitta puts a problem in the way. Solve it, and you're in. That half-second of craving becomes a rep for your mind instead of another mindless scroll.

The dopamine loop

Your phone trained your brain. Cognitta retrains it.

The apps that eat your attention work by promising a tiny reward for almost no effort. Open, scroll, hit. Cognitta breaks the cycle by inserting one demand the loop can't skip: solve a problem before the reward.

The craving loop

Effortless reward, on repeat

  • 1 A flicker of boredom or stress
  • 2 Thumb opens the app on reflex
  • 3 Instant, effortless dopamine
  • 4 The loop gets a little stronger
The Cognitta loop

Reward, but make it earn the entry

  • 1 A flicker of boredom or stress
  • 2 A problem appears before the app
  • 3 You think — and choose, or walk away
  • 4 The reflex weakens; the mind gets a rep
No new habit to build

It lives in the moment you'd reach anyway.

You don't schedule training. It happens in the exact second you'd otherwise open an app without thinking.

1

Guard your apps

Pick the apps you open for a quick hit — social, news, anything you reach for too often.

2

Open as usual

Tap the app like always. Cognitta steps in the instant before it loads.

3

Solve the problem

A randomized challenge appears. Set it to require 1, 2, or 3 to get through.

4

Enter on purpose

Solve it and the app opens — now you're there by choice, not by reflex.

What your brain solves

Six kinds of problem. Pick your training.

Toggle the types you want in Settings. Each one is randomized and pulls on a different mental skill — so your brain never autopilots the same problem twice.

Math

Fast mental arithmetic that keeps your number sense quick.

Numeracy

Sequences

Spot the rule and predict what comes next.

Working memory

Logic

Step-by-step deduction and lateral thinking.

Reasoning

Patterns

Recognize visual and numeric structure at a glance.

Pattern recognition

Inhibition

Stroop-style challenges that train you to override the obvious answer.

Impulse control

Visual

Hold and recall what you just saw, or find the target fast in a field of distractions.

Memory & attention
Your cognitive profile

Watch the reps build a score.

Cognitta keeps an honest record of your mental activity — a Fitness Score, a level you climb, and per-skill progress. No leaderboards, no pressure. Just momentum you can see.

Built for privacy

Everything stays on your phone.

No account, no servers, no data collection. Cognitta uses Android's Accessibility Service for one purpose only: to notice when you open a guarded app, so it can show the problem at the right moment.

No account

No sign-up, no email, no password. Install and start.

No data collected

Nothing stored remotely. Nothing shared. Nothing transmitted.

No reading your screen

Cognitta does not read screen content or keystrokes — only that a guarded app opened.

You're in control

Disable the Accessibility permission anytime in Android Settings.

Good questions

Frequently asked questions

What exactly is Cognitta?+
Cognitta is an Android app that puts a quick problem in front of the apps you choose to guard. Reach for a guarded app, solve a short problem, and it opens. It's designed to interrupt the reflex that drives mindless phone use and turn those moments into light mental exercise.
Why "solve a problem" instead of just blocking the app?+
Blocking creates resentment and gets switched off. A problem does something better: it inserts a beat of real thought between the craving and the reward, so you decide consciously whether to continue — and your brain gets a rep either way.
Will this make me smarter?+
We're careful here. Regular practice reliably makes you better at these problems, and a deliberate pause genuinely disrupts compulsive scrolling — those are benefits we stand behind. The broader science on whether training transfers to general intelligence is mixed, so we don't make medical or cognitive-improvement claims. Treat Cognitta as a good habit, not a treatment.
What kinds of problems are there?+
Six types: Math, Sequences, Logic, Patterns, Inhibition (Stroop-style), and Visual (memory and search). You toggle which ones are active in Settings, and choose whether each unlock needs 1, 2, or 3 problems.
Which apps can I guard?+
Any app on your phone. Most people start with the usual dopamine machines — Instagram, TikTok, Reddit, YouTube, X — but you can guard anything you reach for without thinking.
Why does it need the Accessibility Service?+
It's the only reliable way on Android to detect when you've opened a guarded app, so Cognitta can show the problem at the right instant. It's used for nothing else — it does not read screen content, capture keystrokes, control other apps, or send any data off your device. You enable it yourself and can turn it off anytime.
Do you collect my data?+
No. There's no account, no servers, and no analytics that leave your device. Your score, levels, stats, and settings live entirely on your phone.
Is there an iPhone version?+
An iOS version is in development. Because Apple handles app interception very differently from Android, the iPhone experience will be built on Apple's Screen Time framework. Join the list to hear when it's ready.
Is it free?+
Cognitta works without any subscription. Download it, guard your apps, and start. No paywall stands between you and the core experience.

Put a problem in the way.

The next time your thumb reaches for a hit, make it think first. It's free to start.
