NeuroMetric vs BASLN

NeuroMetric – Reaction Time Training NeuroMetric is a simple and focused app designed to train your reaction time, concentration, and mental focus. Each training session lasts 180 seconds. During the session, the screen will change to green at random intervals. Your task is to tap the screen as quickly as possible when the signal appears. The challenge is not only speed, but maintaining full concentration for the entire session. This app is ideal for users who want to improve: - Reaction speed - Focus and sustained attention - Mental alertness under time pressure How it works - Press the (+) button to start a new training session - Tap to begin when the start screen appears - React instantly when the screen turns green - Stay focused for the full 180 seconds - Open Sessions to review recent trainings and track consistency NeuroMetrics keeps the experience minimal and distraction-free, allowing you to focus entirely on training your mind and reactions. Train regularly, stay sharp, and improve your response time with NeuroMetrics.

Measure your actual cognitive performance every morning. Not your heart rate. Not your sleep stages. Your brain. Whoop, OURA, and Apple Watch measure heart rate variability and guess how your brain is doing. Your wearable can tell you your nervous system is stressed. It can't tell you your reaction time is 80ms slower than yesterday. BASLN measures the thing itself. 6 RESEARCH-VALIDATED TESTS. 5 MINUTES. - Psychomotor Vigilance (PVT-B): the gold standard fatigue measure, used on the International Space Station - Spatial 2-Back: canonical spatial working memory test, validated across decades of cognitive neuroimaging research - Digit Symbol Substitution (DSST): the single best predictor of complex operational performance - Color-Word Stroop: executive function and inhibitory control - Arithmetic Verification: processing speed under cognitive load - Trail Making B: cognitive flexibility and task switching YOUR PERSONAL BASELINE Your first 5 sessions establish your personal baseline. Every session after that is scored against your own norm. 0-100 scale. No comparison to population averages. Just you vs you. READINESS ZONES 90-100: Locked In 75-89: Good to Go 60-74: Off Day (recovery protocols activate) 0-59: Impaired CUSTOM CORRELATIONS Track what you actually care about. Define your own variables (creatine, cold plunge minutes, supplement stacks) and see how they correlate with your readiness score over time. Binary, continuous, or categorical. RECOVERY PROTOCOLS Score below 75? Get evidence-ranked recovery recommendations: cold exposure, bright light therapy, strategic caffeine timing, high-intensity exercise, nap protocols. Each ranked by time-to-effect and evidence quality. ANALYTICS Track trends across all 6 cognitive domains. See how sleep, caffeine, exercise, and your own custom variables correlate with your scores. Compare your current performance against your original baseline to catch long-term drift. DATA PORTABILITY Export your full history as CSV anytime.
