Browser Device Tests
Select any of the ten browser utilities below to check your keyboard, mouse, controller, or screen performance with all test results kept locally on your device.
- Typing Speed Test
Measure your typing speed in words per minute and accuracy.
- Reaction Time Test
Check how fast you respond to a visual color change in milliseconds.
- Click Speed Test
Count how many mouse clicks you can register per second.
- Spacebar Counter
Track how many times you can press the spacebar in a set time.
- Mouse Polling Rate Test
Measure how often your mouse reports its position to the browser in hertz.
- Keyboard Test
Verify that every key on your keyboard registers presses and releases properly.
- Monitor Refresh Rate Test
Estimate your screen refresh rate in hertz using browser animation frames.
- Gamepad Tester
Inspect controller button presses, analog stick axes, and trigger inputs.
- Double Click Test
Detect unintended fast double-clicks and check millisecond intervals between clicks.
- Scroll Speed Test
Measure how fast your mouse wheel or touchpad scrolls in pixels per second.

How it works
This directory connects you to ten standalone hardware and input tests that run directly inside your web browser. Each tool relies on standard browser event listeners, high-resolution timers, and animation frame callbacks to measure input timing, event frequency, or display updates. No downloads or plugins are needed. When you complete a test on any individual page, your results and high scores are saved only in your browser local storage on this device.
Steps
First, review the ten cards in the directory list above to find the specific peripheral or input check you need. Second, click the test title link to open that dedicated tool in your browser. Third, follow the on-screen instructions on the chosen page to start the measurement and view your local results.
Controls
The main card on this index page displays ten linked test titles, each paired with a short summary of what that specific tool checks. Below the list, the status line reads Ready to confirm the directory page has finished loading and all links are active.
Examples
If you just bought a gaming mouse, open the Mouse Polling Rate Test to check its report frequency in hertz, then open the Double Click Test to check for unintended switch chatter. If you are inspecting a laptop, open the Keyboard Test to verify every key registers and the Monitor Refresh Rate Test to confirm the display frame rate.
How to read your result
Each tool in this directory reports raw browser-level measurements, such as words per minute, milliseconds, clicks per second, or hertz. Treat these figures as practical checks of how your hardware, operating system, and web browser behave together right now. They are strictly for everyday hardware troubleshooting and casual comparison, not a clinical, psychological, or medical evaluation of your physical abilities.
Reference ranges
Across these tools, typical readings vary by hardware and task: many people land around 40 to 70 words per minute in typing, around 200 to 300 milliseconds in visual reaction time, and around 5 to 8 clicks per second in standard clicking, while office mice and displays commonly report near 125 Hz and 60 Hz. These rough ranges are never a medical, psychological, or clinical scale.
Tips
For consistent results on a desktop or laptop, close heavy background tabs, disable browser extensions that intercept keystrokes or mouse events, and plug wireless peripherals into power if battery levels are low. On a phone or tablet, turn off low-power or battery-saver modes, clean the touchscreen, and hold the device steady on a flat surface.
FAQ
What do the tests in this directory measure?
The ten tools in this directory measure browser-detected input events and display frame timing, such as key presses, mouse clicks, scroll events, controller inputs, and screen refresh intervals. They do not measure raw electrical signal latency at the hardware level, and they do not provide any medical or clinical assessment.
Why can two runs on the same device differ?
Browser measurements depend on your operating system event queue, CPU load, power-saving settings, and background tabs. Even minor shifts in system activity, wireless interference, or how you position your hand can change timing and frequency numbers slightly from one run to the next on the exact same computer or phone.
Can I run these device tests on a phone?
Yes, you can open this directory on a phone or tablet. Tests for reaction time, tapping speed, scrolling, and screen refresh rate work directly with a touchscreen. Tools designed for physical keyboards, mice, or gamepads require connecting a compatible USB or Bluetooth peripheral to your mobile device to register inputs.
Where are my test results and scores stored?
All test measurements and saved personal records stay inside your browser on this device. Individual tools may use your browser local storage to remember your top scores between visits, but nothing is ever collected, transmitted, or uploaded to external servers. Clearing your browser site data removes any saved local scores.
What do high and low test results usually mean?
Depending on the tool, a higher number usually indicates faster typing or clicking speed, a higher mouse report rate, or a smoother monitor refresh rate, whereas in reaction or double-click timing, lower millisecond values indicate shorter intervals. These numbers simply reflect current device and browser behavior, never a health or psychological diagnosis.
