Each health app is a complex intervention with various features and functions tailored to the users’ needs to promote health and improve their quality of life. Almost all health apps contain information and education, mostly coupled with decision-making aid for the users under the form of recommendations (Davies & Mueller, 2020).

Another feature of health apps is the behavior change support, which can be materialized in reminders and different other nudges.

Self-assessment and monitoring are other functionalities that health apps use for keeping track of symptoms over time and helping medical providers with decision-making on the type of treatment. mHealth features also include communication and interaction using varied device functionalities (e.g. messages, video calls, etc.) to facilitate rapid communication (Davies & Mueller, 2020).

Finally, one essential feature for health apps is the theory-based interventions, meaning the health app is grounded in an existing and tested theory for behavior change. All these features increase the usability and success of health apps in improving people’s lives (Davies & Mueller, 2020).
