Build an android app for our Spotilist project!

We are a group of friends from Denmark, working on developing a website. We want to outsource the development of a mobile android app of the website that we have created.

Our project is supposed to resemble a spotify-like website where you have the ability to sign up, login and follow playlists.

The website we have created is getting information from our own REST-api deployed on our backend. Our backend is using the spotify api to get data. We would like the app to look similar to our website.

The requirements of the application is:
- App developed for android
- App must be responsive
- Any language (react native preferred)
- User must be able to sign up
- User must be able to login
- User must be able to see the 10 most popular playlists
- User must be able to browse playlists by genre
- User must be able to click on playlists to see all tracks
- User must be able to follow playlists
- User must be able to see what playlists they are following

Information about design
