What Volume Booster: Bass Boost EQ does
Boosts and shapes audio played inside the app, either a built-in demo or files you import, with a 10-band equaliser and one-tap A/B comparison.
- Best for: people who want their own audio files louder, or want to hear what an equaliser does.
- Worth knowing: It cannot boost Spotify, YouTube, phone calls or the system volume, because iOS does not let any app do that.
- Price: Free with ads. A rewarded ad unlocks up to 800% boost for the session, and a one-time Remove Ads purchase keeps it unlocked.

Is the 800% boost free?
