This app will run passively in the background of smartphones collecting behavioural data (commonly called digital phenotyping), namely: the number of texts received and replied to, the number and length of phone calls, the number of incidences and time spent on social media or the internet, the total time spent actively using phone and the time spent using the phone at night, the periods of time when the phone is not used. It is important to note the app cannot collect information on what sites were visited or the content of any conversations, messages, or information that is shared.


 


In addition to collecting this information, there will the app will display questions once a day relating to how your day is going. These should take approximately one minute to complete each day.


 


The data collected from app will be compared against mental health data (not collected via this app but at a different place and point in time).
