According to Popular Science, the app uses a variety of data – such as your location, social activity and physical activity – to determine if a person is behaving normally. If a person is not, the app can do things to help the user overcome his or her negative feelings. For starters, Mobilyze can automatically text the user's family and friends, hoping to spark a motivating conversation. Alternatively, it can text the depressed user and attempt to persuade him/her to reach out to a friend or to get out of the house.
