The Fun Star app is an application for community-based volunteers who belong to the Fun Care Net (non-profit organization).
'FUNstar' is the nickname of FunKNet's community-based volunteer activists, and they are volunteers who have completed certain specialized training to help those who are preparing for daily rehabilitation after hospital treatment including severe treatment.
Access rights such as login to the Funstar app are issued through FunKNet.
( Those who are not volunteers affiliated with Funcarenet cannot use the Funstar app.)
