Is your brain younger than yesterday? Find out in 3 minutes, then train 5 a day — 63 games, 13 assessments, an on-device AI coach. New: Daily Challenge.
How old is your brain today?
Synaplay is a pocket brain gym built on classic cognitive-science drills. About 3 minutes of quick calibration games set your personal baseline — a Cognitive Brain Age snapshot you can revisit any time. From there, Synaplay builds a personalized 5-minute daily plan, and your on-device AI coach keeps you company along the way. The goal is simple: beat yesterday's you.
A FULL COGNITIVE CHECKUP — 7 MODULES
A seven-part cognitive battery covering memory encoding, processing speed, attention switching, working memory and delayed recall: word encoding, clock reading, symbol matching, Trail Making A & B, spatial working memory and delayed word recall — all scored against age-based norms.
13 SCIENCE-BASED ASSESSMENTS
• Visual matrices — nonverbal fluid reasoning in the Raven's style, with an estimated IQ and percentile
• Big Five personality (IPIP-50) — your five-trait profile in about 6 minutes
• Impulsivity self-check (BIS-11)
• PHQ-4 quick mood check-in and ISI sleep index
• Brain dominance, cognitive reflection (CRT), divergent thinking (DAT), balloon risk task (BART) and semantic fluency
• Alertness Test (PVT) — a 3-minute simple reaction-time check that reads how alert you are right now
• Corsi Blocks — reproduce ever-growing sequences of blocks to measure your spatial memory span
• SBTI social style profile — 16 playful types, just for fun
63 BRAIN GAMES ACROSS 5 DOMAINS
• Logic: Sudoku, Nonogram, Ball Sort, Tower of Hanoi, Mines, Loopy, Bridges, Pearl and more
• Memory: N-Back, Match The Pair, Wizard Memory, Number Recall and more
• Attention: True Hue (Stroop), Schulte Grid, Double Trouble and more
• Mental Math: Percent Hero, Operator Quest, Math Stick and more
• Spatial: mental-rotation puzzles, Tri Fill, Shape Fall and more
Every game ships with dozens of hand-tuned levels that ramp up as you improve.
