Show HN: RWP – An Android App to keep your wallpaper fresh

I have built an Android app with a friend since 2 months and everythings's finally live. (you can check the announcement post here: https://creekorful.me/pimp-your-phone-like-never-before/) The application allows users to customize their phone with HD wallpapers grouped by categories. You don't have to choose the wallpaper anymore, you'll just need to select the things you like, set the change interval and let the app do the magic!

The technical stack is composed of 2 big parts:

- The native android application (written in Java&Kotlin because we needed access to low-level API).

- The API (written in Go) that communicates with a MongoDB. The API is used to abstract the different wallpaper providers that we use.

Authentication, analytics and user management are done using Google Firebase.

The whole stack is deployed on a Docker Swarm and routing stuff is done using Traefik.

Feedback is welcome ! And It would be a pleasure to answer any question (technical or not)
