VOL·GO is an app that helps high school students find volunteer opportunities more easily. we hope that high school students can use the app to quickly locate the type of volunteer activities they are looking for and that they can share their volunteer experiences through the app so that more people can learn about the real feelings that different volunteer activities bring to people. We also consider the security issue, so the app itself is school-based, and high school students have to register their accounts by logging into their student accounts, which can also better protect the students’ safety.
