Device compatibility
Volume Booster requires iOS 16 or later, and there is an Apple Watch companion for previewing what you have set up. It boosts the audio it plays itself — your own music and audio files — which is the only thing iOS permits any app to do. It cannot raise the system volume or make other apps such as Spotify or YouTube louder, and we would rather say that here than have you find out after installing.
Questions before you install? See the FAQ or read how the app works in How it works.
Make your music louder than ever.
Boost the volume, add deep bass, and fine-tune every track with a 6-band equalizer — all in one simple app.
