Most brain games just hand you a score. SynapseGym shows you something more useful: where your mind is actually sharp, where it slips, and exactly what to train next. A REAL COGNITIVE PROFILE Take a short check and see yourself across six core skills — working memory, attention, processing speed, flexibility, impulse control and planning. No vague number. A clear picture of your strengths and your blind spots. TRAIN WHAT ACTUALLY HOLDS YOU BACK SynapseGym finds your weakest skill and builds a short daily session around it. No random games — focused practice aimed at the one thing that moves the needle for you. SEE REAL, MEASURABLE PROGRESS Re-check every couple of weeks and watch the numbers move. Track your reaction time, follow your streak, and learn the hours when your mind is at its sharpest. GROUNDED IN REAL SCIENCE The exercises are built on established cognitive tasks — Stroop, N-Back, Go/No-Go, digit span and more — turned into quick, sharp sessions that feel like play, not homework. MORE THAN GAMES A sharper mind needs a calmer one. Built-in meditation, gratitude journaling and habit tools help you stay focused and steady, every day. Leaderboards and achievements keep you coming back. 66 EXERCISES — NEVER THE SAME WORKOUT TWICE • Mental math, arithmetic drills and number sequences • Digit span, sequence memory and episodic recall • Stroop, Flanker, Go/No-Go and vigilance for attention • Single and dual N-Back for working memory • Reaction time, processing speed and visual tracking • Trail making, task switching and card sorting • Anagrams, verbal fluency and mental rotation NO ADS. EVER. 38 exercises are free. Premium unlocks all 66 — monthly, yearly, or a one-time lifetime purchase. Train a few minutes a day. See your mind get measurably sharper. SynapseGym is a training and self-assessment tool — not a medical device or a diagnosis.
