Mobile health (mHealth) has become a common and mainstream growing field of intervention delivery in the health technology domain. The focus of mHealth research has been the evaluation of efficacy of the delivery of the provided interventions with limited regard to user engagement. However, mobile apps usage statistics show that users tend to quickly stop using apps, partially due to apps failing to sustain the user’s attention long-term and to provide limited engagement features. We are investigating the effectiveness of different user engagement strategies and to use analytic approaches to design the delivery of the interventions of mHealth apps.
