CogTracker vs Human Benchmark
Human Benchmark gives you a percentile. CogTracker shows why your score changes — and which lifestyle habits to fix.
Human Benchmark is a collection of 9 reaction and memory tests that rank you against everyone else who has ever visited the site. Great for a fun one-off check — your reaction time is faster than X % of people.
CogTracker compares you to yourself. After every session you log sleep, caffeine, exercise, and stress; the AI correlates those inputs with your cognitive score, and after 5 sessions it unlocks a heatmap showing which factors most affect your personal results.
Different goals, different tools. If you want a global percentile for fun, Human Benchmark does that well. If you want to know why your brain feels foggy today — or whether melatonin, a keto diet, or a new supplement actually improves your cognition — CogTracker is the right fit.
Feature comparison
| Feature | Human Benchmark | CogTracker |
|---|---|---|
| Primary goal | Compare your reaction time to a global leaderboard | Track your own cognition over time and correlate with lifestyle |

| Lifestyle correlation | No | Yes — sleep, caffeine, exercise, stress, hydration, screen time |
| AI-powered insights | No | Yes — per-session breakdown; correlation heatmap after 5 sessions |
| Brain fog / health focus | No — general interest / entertainment | Yes — built for COVID fog, perimenopause, ADHD, sleep, stress, chemo |
| Test variety | 9 tests (reaction time, sequence memory, aim trainer, typing, and more) | 4 focused tests (reaction speed, digit span, pattern matching, Stroop) |
| Free tier | Fully free — no sign-up needed | 3 free AI analyses on sign-up, no credit card required |

Who each tool is for
Frequently asked questions
Can't I just track my Human Benchmark scores in a spreadsheet?
You can, but Human Benchmark exports no raw data and does not ask why your score changed. CogTracker's structured lifestyle log plus AI analysis does the correlation work automatically — after 5 sessions it surfaces which factors most affect your specific score.
Does CogTracker have the same tests as Human Benchmark?
CogTracker includes Reaction Speed (similar to HB's Reaction Time), Digit Span (similar to HB's Number Memory), and Pattern Matching (similar to HB's Visual Memory). The fourth test, Stroop Color-Word, has no direct HB equivalent. CogTracker prioritizes the subset most sensitive to brain fog and fatigue.
Is Human Benchmark more accurate for reaction time?
Both tools use JavaScript-based timing, which introduces similar browser-level variance (roughly 15–50 ms). Neither is a clinical-grade instrument. For tracking your own trend the variance cancels out across sessions — relative day-to-day changes are meaningful; single-session absolute values are not.
Should I use both tools?
They serve different goals. Human Benchmark is great for a one-off curiosity check or comparing a specific ability against other people. CogTracker is built for ongoing self-experimentation — tracking how your brain responds to sleep changes, supplements, stress, or recovery from illness over weeks or months.
Is CogTracker free?
The first 3 full AI analysis sessions are free after sign-up — no credit card needed. If you want more, 100 credits cost $9 one-time with no expiry.
