VolumeBooster+: Sound Booster

Volume Booster+ is a volume booster and sound booster that makes your phone louder, with an always-on limiter and dB safety zones. Turn up a quiet speaker, low earphones, or a video that is hard to hear. It works system-wide, so most apps get louder at once.

WHAT IT DOES

• One-tap levels 100%, 125%, 150% and Max: each raises your device volume, then boosts most apps up to 225% (+15 dB), with Safe / Caution / Danger colors based on WHO hearing guidance

• Loudness Maximizer: louder through multiband compression and makeup gain, without clipping

• Always-on peak limiter that keeps the sound clean

• 5-band equalizer with 9 presets, some with bass boost and 3D widening

• AutoEQ: 2,456 measured headphone profiles across 357 brands, matched to your model

• Floating panel to adjust the boost over any app

• Hearing protection: see how much of your listening stayed below the safe level

• Sleep timer with a smooth fade-out (15 min – 2 h) and L / R channel balance

• Quick Settings tile and home-screen widget for one-tap on/off

• Notification controls: gain ±1 dB, preset cycle, A/B compare

GETTING STARTED

1. Open Volume Booster+ and tap Start: your device volume goes up and the boost turns on at 150%.

2. Pick another level (100%, 125%, 150% or Max) or fine-tune with the slider, and watch the color: Safe, Caution or Danger.

3. If you like, pick an equalizer preset or your headphones in AutoEQ.

FAQ

Q. It is not getting louder.

A. Check the device volume on the main screen first: the boost adds on top of it, so at a low volume the difference is small. Tap a level button to raise it. If it is still not louder, open the built-in help; it can switch to compatibility mode.

Q. Is it safe for my ears?

A. The boosted sound always passes through a limiter, and the dB value is shown with Safe / Caution / Danger zones based on WHO hearing guidance. The value is an estimate based on your system volume and the applied gain; real loudness varies by device, headphones and content.

Q. Does it work in every app?

A. It raises the system output, so most music, video and game apps get louder at once without setting each one up.
