5 clinically-inspired tests that measure your reaction time, memory, focus, and motor precision — built for kids, professionals, and seniors alike.
Cognitive performance matters at every age. BrainBoost tells you exactly where you stand — and gives you the tools to improve.
Children and teens benefit most from cognitive baseline testing. Early training builds stronger neural pathways before the brain fully matures at age 25.
Your prime years are the right time to optimize. Whether you're a student, professional, or athlete — your cognitive edge determines your output.
The brain loses ~5% of volume per decade after 40. But research shows consistent cognitive training slows this significantly and preserves independence.
Every person who picks up BrainBoost starts with a number. These are the stories of what happened next.

"My son couldn't sit still for 10 minutes. His teacher said he struggled to follow classroom instructions. His first reaction test score was 420ms — in the bottom 20th percentile for his age."
After 15 minutes of daily BrainBoost training, Arjun's reaction time dropped from 420ms to 290ms. His focus window extended. His teacher noticed improvements in classroom participation within 3 weeks — without any medication.
"I was forgetting meeting details, losing track of multi-step logic at work. I thought it was burnout. My Memory Match score was 34 moves — I couldn't believe how poor my short-term memory had become."
Priya completed BrainBoost's memory tests daily for 8 weeks. Her moves dropped from 34 to 19. More importantly, she started finishing code reviews faster and retaining architectural decisions without notes. "It felt like clearing RAM," she said.
"I started forgetting names. I'd walk into a room and forget why. My doctor said it was normal aging but it scared me. My daughter installed BrainBoost for me. I was skeptical — I'd never played a mobile game in my life."
Mr. Rajan's Sequence Rush level improved from Level 3 to Level 6 over 12 weeks of consistent training. He started tracking his scores himself — and sharing them with his doctor. "Having a number makes me feel in control," he wrote to us.
Each test isolates a different cognitive circuit. Together they build your complete cognitive profile.
Your visual-motor reaction time is one of the most reliable biomarkers of cognitive health. It degrades with age, poor sleep, and stress — and improves with training. We measure it in milliseconds.
Working memory is the mental workspace. Low capacity correlates with poor academic performance, decision fatigue, and cognitive aging. BrainBoost measures yours precisely.
Tracking multiple moving objects tests your parietal cortex — the control tower for spatial attention.
Pattern memory engages the hippocampus and prefrontal cortex — core systems for learning and planning.
Cerebellar timing precision governs everything from sports performance to handwriting to musical ability.
BrainBoost doesn't just give you raw numbers — it compares you against age-matched data and shows you exactly where to improve. Track progress session by session.
Every session is both an assessment and a training session. The act of performing these tasks builds the neural circuits they measure — that's the neuroplasticity principle in action.
"I'm a competitive gamer. My reaction time went from 240ms to 190ms after 5 weeks. That's the difference between winning and losing. BrainBoost is now non-negotiable in my training."
"I use it with my 10-year-old every evening. She loves the games and I love watching her scores improve. It's opened a great conversation about how the brain works."
"At 71, I was worried about my memory. BrainBoost gave me a score I could track. I'm not declining — I'm improving. That peace of mind is worth everything to me."

Cognitive training is not a buzzword. It's grounded in decades of peer-reviewed neuroscience. Here's why it works — and why starting early (or late) matters.
Neuroplasticity — the brain's ability to reorganize its structure — is the scientific foundation of all cognitive training. When you consistently perform a cognitive task, neurons form stronger synaptic connections through a process called long-term potentiation (LTP). This is measurable and real.
Reaction time is the total latency from stimulus to response — involving visual cortex processing, prefrontal decision-making, and motor cortex execution. The theoretical minimum for visual stimuli is ~100ms. The average untrained adult: 250ms. Elite athletes: 150–190ms.
The brain is the most complex organ in the known universe. Yet most people never check on it. Here's what the research tells us.
The prefrontal cortex — governing focus and impulse control — doesn't fully develop until age 25. Early cognitive training during ages 6–17 shapes these circuits at their most plastic, producing lasting effects that outperform later-life interventions.
Ages 18–35 represent peak cognitive processing speed — but this peak is not automatic. Without deliberate training, reaction time and working memory begin subtle decline after 25. Regular measurement lets you catch drift before it becomes deficit.
Cognitive reserve — the brain's resilience to age-related change — is built through active use. People who engage in regular mental training show 40% lower risk of clinically significant cognitive decline. Measurement is the first step to preservation.
A longitudinal study of 412 students showed that 8 weeks of working memory training improved academic test scores by 18% and reduced mental fatigue markers by 31%.
Visual-motor training in adults aged 18–45 produced statistically significant RT improvements of 22% over 6 weeks. Gains persisted for 3 months post-training.
Divided attention tasks significantly improved executive function scores and reduced error rates in complex multi-step decision-making by 27%.
Sequential pattern training activated DLPFC and anterior cingulate cortex — regions critical for planning, inhibition, and cognitive flexibility.
Catch-and-respond drills showed cerebellar adaptation within 2 weeks — improving timing precision and reducing anticipatory errors by 41%.
Meta-analysis of 89 RCTs (n=11,400) confirmed moderate-to-large effect sizes for domain-specific cognitive training — strongest for memory, reaction time, and attention.
The science of cognitive training is rich and validated. But most consumer apps were shallow, gamified, and scientifically empty. BrainBoost was built to change that.
BrainBoost is a cognitive assessment and training app for iOS. It offers 5 tests — each grounded in validated neuroscience — that measure your reaction time, working memory, sequential processing, divided attention, and motor timing. Every session gives you a score. Every score tells you something real.
We believe cognitive health monitoring should be as simple and accessible as checking your blood pressure. We're not trying to replace neurologists or psychologists. We're trying to give every person — a parent, a student, a retired teacher, a competitive gamer — a meaningful baseline for their brain and a way to improve it.
Every test in BrainBoost is designed around peer-reviewed cognitive science. We don't invent metrics — we adapt established paradigms (choice reaction tasks, n-back variations, sequential recall, multi-object tracking) to a mobile format. The Science page covers the specific research that underpins each test.
BrainBoost is available on iOS. It's free to download and use. There are no paywalled tests. The core mission — giving everyone access to real cognitive measurement — is not behind a subscription. We're a small, independently built app. Feedback, bug reports, and kind words are always welcome.
BrainBoost is not a medical diagnostic tool. It does not diagnose ADHD, dementia, anxiety, or any other clinical condition. If you have concerns about your cognitive health, please consult a qualified healthcare professional. Our scores are informational and training-oriented, not clinical.
