Wildpeppers is a project I made for fun between 2019 and 2020 to experiment with Gooogle Firebase. Wildpeppers Android is the Android app front-end that enables users to download wallpapers for their phones from a Firebase database.
It originates from probelalkhan/wallpaper-app-admin.
Wildpeppers wallpapers adopts the Lawnchair launcher's naming approach, just like Emulair emulator does, therefore the name is nothing more than a homophone for the kind of software that Wildpeppers is (a wallpapers downloading app).
The project doesn't work properly and it's not actually available on Google Play ://. Lawnchair is not associated with Wildpeppers.
