I'm looking for an Equalizer app for Android that:
- is very simple and basic but works well
- does not require many permissions
- does not send data to third party (and even, does not use mobile data or Wifi all, that's not needed)
- does not display ads
A simple Equalizer with a few bands that allows the user to increase/decrease the bass when listening to music with Bluetooth speakers.
I searched the Play Store, but I couldn't find an app that has points 1. 2. 3. 4.
