Communicate mobile technologies (CMTs) enable people to work and study from anywhere and at any time. Telework has developed into a new trendy way of living. However, without a consistent schedule, teleworkers may struggle with social jetlag: the misalignment of biological and social time. Circadian disruption has a detrimental effect on people's health. People's attitudes toward circadian rhythms are critical in assisting them in changing unhealthy behaviours. This project will create an application and a tangible sunflower device to encourage users to reflect on their lifestyle choices and to gain a better knowledge of the consequences of circadian disruption in order to motivate users to change their behaviour.

Circadian App is designed to help users in managing their circadian rhythms by tracking their sleep, food, and physical activity. According to their circadian activities record to urge them to reflect on their lifestyle.

Based on the user's circadian rhythm, the sunflower interactive device displays their health state. The change in sunflower behaviour (blooming or closing) is a result of the user's circadian management and is triggered by user behavioural change.
