This is the medaa team's solution to the 12th edition of Polihack, organised by OSUT.
This is a mobile app that provides a tool that makes recycling way easier, solving the main issue regarding the lack of frequency of recycling in our day to day lives.
Creates a community by connecting people on a platform similar to social media, where you can add on the map and leave reviews of different recycling centers nearby you.
The app includes a map that helps you view all the recycling centers added by users or already present nearby you.
The application includes a reward system that stimulates its user to keep on recycling. Every item has a specific number of points that can be viewed after scanning the QR code that the recycling center generates. They are summed up and at certain levels, you can unlock new stickers in the app that you can view.
Every user has an account, safely implemented using Google Firebase. The app therefore includes Sign Up, Log in, Log out and Forgot your password pages that allow you to navigate through the application.

Rewards page
The code is written in Java, using Android Studio. For the user management system and the database, we used Google Firebase.
This is more of a concept of the app, altough fully functional. The proper development of it stopped after the hackathon, but we are looking forward to further developing it.
