Question 1

What are brain tests?

Accepted Answer

Brain tests are short, timed challenges that measure specific cognitive functions like reaction time, memory, attention, and processing speed. They give you objective data on how your brain performs under pressure. On Senwitt, each test uses high-precision timers and hardware latency compensation so your scores reflect real cognitive performance, not device speed.

Question 2

Are Senwitt's brain tests free?

Accepted Answer

Yes. All core brain tests on Senwitt are completely free and require no account or signup. You get instant results and can compare your scores against a global cohort. Pro and Premium plans are available for users who want deeper analytics, cognitive profiling, and AI-powered training recommendations.

Question 3

What is a good reaction time?

Accepted Answer

The average human reaction time for visual stimuli is approximately 250-270 milliseconds. A score under 220ms is considered fast, and competitive gamers typically score between 150-200ms. Reaction time peaks in the early 20s and gradually slows with age. You can test yours instantly with Senwitt’s free reaction time test.

Question 4

How can I improve my brain test scores?

Accepted Answer

Regular practice, adequate sleep, physical exercise, and reduced screen fatigue all contribute to better cognitive performance. Testing consistently — 2 to 3 sessions per week — shows measurable improvement for most users within 30 days. Each test page on Senwitt includes specific tips for improving that cognitive function.

Question 5

Are online brain tests accurate?

Accepted Answer

Online brain tests provide reliable relative measurements — they’re effective for tracking your own performance over time and comparing against population benchmarks. Senwitt goes further than most platforms by using hardware latency compensation, which removes device-related variation from your scores. This makes Senwitt’s measurements more precise than standard browser-based tests.

Question 6

How often should I take brain tests?

Accepted Answer

For meaningful tracking, 2 to 3 sessions per week of 3 to 5 minutes each is optimal. This gives you enough data points to spot trends without test fatigue affecting your results. Senwitt tracks your performance history automatically so you can see improvement over time.
