The "Carer Bond" mobile application is produced by the Christian Family Service Center. The application aims to provide a one-stop online interactive platform. The program includes three major functions: 1.⁠ ⁠ "Fake Caregiver" Support Matching 2.⁠ ⁠Volunteer Service Matching 3.⁠ ⁠Transfer of Rehabilitation Materials Support and matching service for "Fake Caregiver", hoping to recruit and train enthusiastic community members. Leave-taking caregivers must complete specific courses and complete relevant assessments before they can provide relevant services. "Replacement Carer" provides short-term home care services so that carers who have been taking care of the elderly alone for a long time can take regular breaks. Through mobile network coverage, caregivers can find helpers in the community more conveniently and quickly, and can flexibly arrange care for relatives and friends, thereby reducing the burden on social resources and serving more elderly families in need in the region.
