This app is a research project attempting to show flaws in the way how
audio advertisement is shown on Android. It is a proof-of-concept of a
modularized audio ad blocker written in Kotlin with a modern and
simplistic user interface.
- Support for Spotify (Lite), Soundcloud, Deezer, Accuradio
- No root required
- Plugin based design
- Mute audio when ads are playing
- Play arbitrary audio
You can pick from one of three options to play instead of the ad:
1. Mute audio
2. Local music files
3. Interdimensional Cable from Rick and Morty (discontinued)

How to install
Download the APK from the button at the top of this page.
Allow “Install unknown apps” for your browser or file manager only, not for every app.
Open the downloaded file and confirm the installation.
If installation fails with “App not installed,” remove an earlier build of the same app first. A signature conflict is the usual cause.
