How it works
Start the test, wait for the panel to turn green and click as quickly as possible. Your average is calculated over five rounds. Nothing is uploaded and no account is required.
Useful to know
Results vary with your display, browser, input device and attention. Use the same setup when comparing sessions.
Private by design
Inputs, selected files and results stay inside your browser. Perkforge does not receive the content you process with this tool.
