What to test in Speed & Reaction
Speed and reaction challenges separate several kinds of fast performance: simple visual response, repeated clicking, typing speed, keyboard response, and choice reaction. Use the individual tests to see whether your strongest results come from raw response time, sustained input speed, or quick decisions.
Reaction Time
Best starting point for a simple visual cue and click/tap response.
Click Speed (CPS)
Use when you want a short sustained clicking-speed challenge.
Typing Speed (WPM)
Measures text-entry speed while accuracy still matters.
Choice Reaction Time
Adds a directional decision before the response.
Keyboard Reaction
Uses the spacebar to remove pointer movement from the response.
How to compare your results
Compare the same test, difficulty, device, and input method across sessions. Mouse, keyboard, touchscreen, display, and browser latency can affect absolute times, so your own trend under similar conditions is the most useful benchmark.
All Ruth Performance Lab scores stay in local browser storage. These challenges are recreational personal-performance tools, not medical, psychological, educational, or employment assessments.
Compete against your own baseline
These challenges are designed for repeat play. Device, browser and input hardware can affect results, so the most useful comparison is your own score history on a consistent setup.
All scores are stored locally in your browser. They are recreational measures, not medical, psychological or diagnostic tests.

Frequently asked questions
What do speed and reaction challenges measure?
They record browser-based response, clicking or typing results so you can compare repeated attempts on the same device.
Are reaction scores medical measurements?
No. These are recreational browser challenges and are not diagnostic or clinical tests.
How can I use these challenges?
Repeat the same challenge under similar conditions and compare your own recent runs and personal bests.
