About this app

Most apps are designed to be opened without thinking. Cognitta turns those moments into a daily cognitive workout.

Every time you open a guarded app, Cognitta presents a quick problem — math, logic, sequences, or focus challenges. Solve it, and the app opens instantly. It takes 10 seconds. But those 10 seconds add up to a sharper, more active mind.

Your brain is a muscle. Cognitta is the gym.

Most people solve 5–20 problems a day without even trying — just by going about their normal phone use. Cognitta fits cognitive training into moments that already exist in your day, no extra time required.

What kind of problems?

- Mental arithmetic — fast calculation to keep your number sense sharp.
- Logic problems — deductive reasoning, set membership, and odd-one-out.
- Number sequences — pattern recognition and working memory.
- Pattern recognition — Raven's-style matrix reasoning.
- Inhibition challenges — Stroop-style tests for focus and impulse control.
- Visual memory — recall and compare what you just saw.

Each problem is generated from a bank of over 150,000 stems across six categories — your brain never autopilots through the same problem twice.

Who is Cognitta for?

Accessibility Service disclosure

Cognitta uses Android's Accessibility Service to detect when you open a guarded app so it can present the problem gate at the right moment. This is the only way to reliably detect foreground app changes on Android. The Accessibility Service is used solely for this purpose. It does not read screen content, capture keystrokes, record audio, control other apps, or transmit any data. You can disable the service at any time in Android Settings.
