Reporting a problem
If a test misbehaves or a score looks wrong, these details help us reproduce it:
- the page and the mode you chose (for example “CPS test, 10 seconds”);
- your device and browser, such as “Windows laptop, Chrome” or “iPhone, Safari”;
- whether you used a mouse, touch screen or keyboard;
- the refresh rate shown in the “Your setup” box;
- what you expected and what happened instead.
Corrections and ideas
Spotted an error in an explanation or a source that has moved? Want a test we do not have yet? We would like to hear about it.
What we cannot do
We cannot look up or restore your scores — they are stored only in your browser, never on our side. And we cannot give medical advice about reaction time or memory.
