Before you run

Get a cleaner answer

  • Use the actual device, control, or output you want to check.
  • Allow camera or microphone access only when that test asks.
  • Browser privacy limits are shown as unsupported, not as failures.
  • Repeat the interaction if you want to confirm a fault.

Useful context

Common questions

What does the reaction result include?

It includes your response plus delay from the display, browser, operating system, and input device. For fair comparisons, repeat the test on the same device and browser.

Why are there five attempts?

A randomized five-attempt average reduces the effect of one lucky guess or distraction while keeping the test quick enough to repeat.

Troubleshooting

Fix common problems

Results feel inconsistent

  1. 1Keep this tab visible and place your pointer or finger on the panel before each attempt.
  2. 2Use the same input device and display mode for comparisons.
  3. 3Run another five-attempt set and compare the averages instead of single attempts.
