Smartphone app and design system for experience sampling/ecological momentary assessment research. Smartphones have changed the way we live and, increasingly, they will change the way we understand ourselves. As a result of recent advances in technology, it is now possible for surveys to be replaced by smartphone apps that can capture our daily experiences, offering new insights and greater understanding. Whereas surveys provide a “snapshot” into a person’s life, smartphones present the possibility of getting multiple glimpses of a person’s daily experience as they experience it. LifeData makes that possibility a reality. People benefit from a better understanding of themselves through more accurate observations, positive reinforcement, and guidance in the everyday moments of life. The LifeData system helps make this simple and effective through the use of smartphones and web services. The combination of these applications can be used for prompting changes in thought and behavior within daily routines. The LifeData suite of applications provides unprecedented flexibility and effectiveness for those wanting to collect & visualize real-time information about people. Create graphs to visualize data as it streams in, track response rate or simply download your data. No other system exists to delve into the human experience to this level. LifePak builders and RealLife Exp users can gain new insights, develop positive habits, stay motivated, be more productive, and more. OUR MISSON: We use real-time, mobile technology to help people better understand themselves and more intentionally live the lives they imagine. - Reaching people in the everyday moments of life - Fostering a deeper understanding of people - Helping people flourish and live healthy lives
