How to define the user's tolerance of response time in using mobile applications

System response time can greatly affect the user experience. Society has entered the mobile Internet era, and in mobile applications, as carriers of the mobile Internet, response time is an important performance index related to users' attention. Previous studies of user experience of response time have focused more on computers and websites and less on mobile applications. The current study develops an evaluation program for researching user experience of response times in mobile applications; this simulation enables users to give subjective evaluations. The results indicate the following: (1) with an increase in response time, evaluation scores gradually decrease; (2) the relationship between response time and the subjective experience of users fits a logarithmic function, which can provide relevant references for determining mobile applications' response time; and (3) this article provides insight into performance standards related to response time for mobile applications.
