Volume Booster+: Sound Booster

Is your phone too quiet? Volume Booster+ makes it louder. Turn up quiet speakers, low earphones, hard-to-hear videos, music and games so you finally hear them clearly. It works system-wide, so most apps get louder at once.

The boost is shown in decibels, up to +15 dB, with Safe / Caution / Danger zones based on WHO hearing guidance — so you always see how far you have pushed it.

Please listen responsibly. The decibel value shown is an estimate based on your system volume and the applied gain; real loudness varies by device, headphones and content. This app is not a medical device — if you notice ear pain, ringing, or any change in your hearing, lower the volume and consult a professional.
