Psychologists (professional and hobbyists), teachers, and others who need to measure response times in various scenarios such as in distraction and stress environments - use mReactions to create tests to measure response times to audible or textual stimuli, with the number of stimuli, a repeating or singular stimuli, and the time variance between the stimuli (including within a range) with a maximum response time all set on a per-test basis. The test results provide a basic analysis of the results (mean, minimum, maximum, standard deviation and variance of the response times) with the ability to export the test results as a standard csv file for further analysis and aggregation. The responses to the stimuli are made by either touching the devices screen or through the use of a bluetooth enabled device which can emulate a "space bar" press.
