NeuralFit

Ten science-inspired micro-tests for your reflexes, focus, and memory. See exactly how each score is calculated, and watch your real progress over time.

How fast are you, really? How steady is your hand? How sharp is your focus right now, at this exact moment?

NeuralFit is a pocket lab for your nervous system — ten quick, science-inspired micro-tests that measure how fast, steady, and sharp you are, each one under 30 seconds.

TEN MICRO-TESTS

• Reaction — tap the instant the screen turns green • Steadiness — hold your finger perfectly still • Rhythm — tap in time with a metronome beat • Memory Flash — repeat a growing sequence of flashing tiles • Go/No-Go — tap on green, hold back on red • Tap Speed — how many taps can you land in five seconds? • Stroop Match — does the word match its ink color? • Aim Trainer — hit moving targets fast and clean • Number Memory — how many digits can you hold in your head? • Tilt Balance — keep a bubble centered using your phone's motion sensor

DAILY QUICK CHECK

Run Reaction, Steadiness, and Rhythm back to back for one combined Bio-Reflex Score — a 30-second daily check-in on how sharp you are today.

EVERY SCORE EXPLAINED

NeuralFit never shows you a bare number and leaves you guessing. Every test has a plain-language "How it's scored" explainer, and every result comes with the real unit behind it — 412ms median, 88% correct, 6 digits recalled — not just an abstract 0–100.

TRACK YOUR ACTUAL PROGRESS

The Progress tab charts your recent runs for any test, shows your best and average, and tells you plainly whether you're trending up or down. Personal bests are tracked separately for every difficulty setting, so a 3-trial Reaction PR and a 10-trial Reaction PR are never confused with each other.

MAKE IT YOURS

Every test is fully configurable — trial counts, hold durations, tempo, target size, digit span, and more, all on sliders with no fixed presets. Pick from four accent themes and light, dark, or system appearance.

FREE TO START

Scores are for fun and self-tracking — NeuralFit is not a medical device and does not provide medical advice or diagnosis.
