"If people cannot write well, they cannot think well,
and if they cannot think well, others will do their thinking for them."

What you'll train

Four pillars of a sharp mind

Each session covers all four cognitive dimensions — not just the ones you're already good at.

Memory

Sequence recall, pattern memorization, famous faces. Remember names, places and everything that matters.

Logic

Chess puzzles, IQ-style matrices, Liar's Grid, Sudoku. Think faster and solve harder problems under pressure.

Speed

Stroop challenge, Math Sprint, reaction training. Sharper reflexes and faster decision-making in real life.

Culture

Art recognition, geography, architecture, famous people. Know things — not just know how to Google them.

In-app experience

Common questions

FAQ

Yes — Cogni is completely free on Google Play. A premium plan unlocks all game modes, streak protection and deep brain analytics. The core daily training is free forever.
The standard daily warmup takes about 5 minutes and covers 5 cognitive areas: Memory, Math, Art, Geography, and Stroop. Individual games can be played on top of that for as long as you like.
Cogni targets four areas: Memory (sequences, faces, patterns), Logic (chess puzzles, IQ matrices, grid problems), Speed (Stroop, math sprints, reaction time) and Culture (art, geography, famous people, architecture). Each area has dedicated games and is tracked separately in your Brain Insights dashboard.
Regular cognitive exercise strengthens neural pathways. Cogni tracks your reaction time, accuracy and Brain Score over time so improvement is measurable — not just felt. Consistency is what drives results: 5 minutes daily outperforms occasional hour-long sessions.
Cogni is currently available for Android on Google Play. An iOS version for iPhone and iPad is actively in development — download the Android version now and iOS is coming soon.
Precisely because of AI. As automation handles routine thinking, uniquely human capacities — creative reasoning, memory, judgment, cultural depth — become more valuable, not less. Cogni helps you maintain and grow the cognitive edge that no algorithm can replace. People who stop exercising their minds risk having their thinking outsourced entirely.
