Expo Tree allows you to track the position of the "tree of life" (Albero della vita, in Italian), the symbol of Expo 2015 in Milan, Italy.
- Are you curious to see what's that distance between you and the tree?
- Are you driving in the highway and you want to be sure to see the tree from the window of your car?
- Do you want to know how to get to one of the official parking?
- Do you want to share your "distance to the tree" with your friends?

Thus this App is for you!!
