This is a simple tool to measure your reaction time.

Response time is the sum of reaction time and movement time. Usually the focus in research is on reaction time. There are four basic means of measuring it but in this app we use only one:

- Recognition or Go/No-Go reaction time tasks require that the subject press a button when one stimulus type appears and withhold a response when another stimulus type appears.

Warning: Each device is different and there may be additional delays depending on the number of background processes and the age of the device.
