With caTrée, family caregivers are trees in a forest of care. Family caregivers, especially those providing long-term care, face significant burdens due to a lack of support and time to seek help. caTrée highlights social support through a tree-shaped stand and an online community platform, fostering network awareness, connections, and resource sharing. The tree stand symbolizes caregivers’ support networks, while the app facilitates knowledge-sharing and connections among caregivers. By leveraging social support and emphasizing the value of relationships in stress management, caTrée helps caregivers manage their roles while tending to their own well-being.
