Research on this App

“Purple Chill” is part of the Intellicare Suite of mental health apps by the Center for Behavioral Intervention Technologies. A 2017 trial of the Intellicare Suite found that users of the Intellicare apps showed a reduction in symptoms of depression and anxiety after using 5 or more apps in the Intellicare suite over eight weeks. Another study by Lattie et al (2015) presents the uptake and usage of apps from the IntelliCare suite following an open deployment on a large app marketplace. In the first year of public availability, 5210 individuals downloaded one or more of the IntelliCare apps, for a total of 10,131 downloads. Nearly a third of these individuals (31.8%) downloaded more than one of these apps. The modal number of launches for each of the apps was 1, however the mean number of app launches per app ranged from 3.10 to 16.98, reflecting considerable variability in the use of each app.
