Okto: Brain Training & Tests

Train your brain. Grow your wrinkles. Okto turns five minutes a day into progress you can actually see — and a companion that evolves as you improve. Most brain training apps hand you a score and leave. Okto gives you a character. Your octopus starts smooth-brained at one wrinkle and gains a new fold with every rank you earn. Ten wrinkles. Ten evolutions. Every one of them earned. WHAT YOU GET 40+ games across five skills. Memory, Focus, Speed, Logic and Reaction — each with its own set of games, its own score, and its own trend line. The Wrinkle System. Ten ranks that gate harder games and new evolutions. Your rank card is shareable, so you can find out whose brain is actually wrinklier. Cognitive Type Test. Discover whether you're a Strategist, Sprinter, Analyst or Sentinel, and see how your type shapes the way you solve problems. Real measurement. Reaction time against global averages. Working memory span. Sustained attention. Percentile ranking against players your age — not participation points. Recovery Mode. Guided breathing to reset focus between sessions. Train hard, recover properly. HOW IT WORKS Okto builds your daily workout from the games your profile needs most, adapts difficulty as you improve, and tracks a streak so the habit holds. Everything works offline. Five minutes is enough. WHO IT'S FOR Students before exams. Professionals who want sharper focus by 3pm. Anyone who wants training that respects their time and shows the numbers instead of just handing out points. FREE TO START Core games, daily training and your first test are free. Okto Premium unlocks the full library, every cognitive test, unlimited replays and detailed analytics. Okto is designed for mental training and entertainment. Brain training is practice, not medical treatment, and results vary between individuals. Download Okto. Start at one wrinkle. See how far you get.
