We concluded that individualized follow-up via an app is a feasible and effective method of promoting adherence to healthy behaviour post cardiac rehabilitation (CR).
Our review also demonstrated limited research of the use of apps for lifestyle improvement in non-communicable diseases (NCDs) other than diabetes. For diabetes, the use of apps seems to improve lifestyle factors, resulting especially in decreased HbA1c.
More research in this field is needed, particularly in terms of app-based interventions that promote adherence to healthy behaviour with consideration for the complexity of the process of adherence, long-term adherence and implementation.
