Let’s imagine a common citizen who must travel for many kilometres to join his office or he needs to move through the streets of Milan. He certainly has few possible choices and probably he will opt for the most convenient or the one that required less time. Our objective is to help him in this choice by selecting some alternatives and addressing him towards a solution that could also be eco-friendly. For this reason, we designed a platform which connect other existing applications providing services or products that are pro-environment. In particular, we decided to put in contact all the company interested in the viability of Milan. We thought to involve in that project the Public means (ATM), the bike sharing (Ofo, Mobike, Bikemi), the car sharing (Car2Go, Enjoy, Share’n’go, Ubeeqo, DriveNow, E-Vai), the scooter sharing (Mimoto, Ecooltra) applications. Then, MiLavo will embrace also the applications like Health that monitor physical activity of the users, for example steps and kilometres realized by walking. Our Platform provides the available means nearby and compare all the results that are eco-friendly by consulting the existing applications. In this way the common citizen of Milan can easily compare all the possibilities and he can find a way to move without resorting to his private car. In a certain sense our platform was created in order to push the residents to leave their own car preferring other means that are more sustainable. 
We believed that the most effective way to attract users is to create a system of awards and recognitions. In this manner the common citizen, by using Milavo platform, will be able to get points based on the services he will choose. Every user will have a personal tree which will grow up with the increase of the score. At the achievement of a certain amount of points (1000 pts) there will be the possibility to plant a real tree in a park, in according with the municipality of Milan. Moreover, the applications that are involved in this project will provide special monthly awards like for example, free tickets, coupons and discounts. We established a precise graduation that will assign to every service a certain amount of points. For example, the use of an electrical car sharing will give the possibility to get more points than the choice of an oil one. In this way by managing a very eco-friendly behaviours, users can easily get a lot of points and make growing their personal tree very quickly. 

Each user will have also the possibility to share his results on the social networks like for example the number pof trees that will be planted and the weekly or monthly rankings which will put in competition the users in all the city. We thought that today Facebook and Instagram stories are the platforms that suit more for this kind of activity. Moreover, there will be the possibility for the users to become volunteer or potential tree planter which will permit to receive higher rewards. The necessary material and all the information will be provided to the volunteers in a way that they know where and how to plant the tree.
To conclude, an effective app would not survive without the reviews. We are sure that the opinion of the users is fundamental and essential for the development and the improvement of the Milavo platform. For this reason, we introduced the possibility to share opinion and to signal some eventual problems that the citizen will found using our app. The reviews aim to create competition among the existing apps in a way that they will be pushed to innovate themselves continuously. 
The solution we had designed came out from different principles. These were the results of the analysis we have made at the beginning of our work. In particular, we focused on the idea of creating a community of people based on the sharing and the entertainment. In fact, by creating Milavo we had realized a common platform which encourage eco-friendly behaviours providing many rewards and advantages for the users.
