High Five is a team building app that inculcates team building, team coordination among teams by way of certain games. For someone like me who has to do most of the assignments in a group, functioning with a team is a really challenging task. Team Coordination is the most important thing which one should learn as it really helps you once you start working. I would rate it 5 because I think the idea is very unique and the team building is a complex task and the app is solving this problem.
