Cognitta

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.

Built for privacy

Cognitta works entirely on your device. No account required. No data collected. No servers. Everything stays local.
Cognitta uses Android's Accessibility Service solely to detect when a guarded app is opened so it can present the problem gate. It does not read screen content, capture keystrokes, or access any data from other apps.

Who is Cognitta for?

Anyone who wants to stay mentally sharp without carving out extra time in their day. If you already pick up your phone dozens of times a day, you already have everything you need for a daily cognitive workout.
