With a rapidly ageing population in Hong Kong, there is a need to provide more volunteer services to the elderly. We introduce HINCare, an app that encourages mutual-help in the community. HINCare adopts the concept of timebanking, where each user has his/her own account to store the amount of time (”time credits”). Users earn time credits by providing services to others. The user can use the time credits to purchase other services. Moreover, HINCare uses HIN (Heterogeneous Information Network) to recommend helpers to elders.
