he iPhone and similar smartphones have been described as addictive technologies [5]. Survey-based research has shown that many respondents would give up brushing their teeth, having sex, exercising, wearing shoes, showering, and eating chocolate instead of living without their iPhone for the same period of time [6]. There have been a number of empirical studies relevant to addiction to smartphones (see [7] for a review) and the prevalence of mobile phone addiction varies widely from study to study, with mobile phone addiction rates reported in the range of 0-38%, depending on the study and the scale used [7]. Researchers also differ in the extent to which mobile phone addiction is actually problematic. Some argue that mobile phone usage is rewarding and, like any other rewarded behavior, the addiction to mobile phones is quite prevalent, but not problematic [8].
