SoundBooster: Volume Booster

Music too quiet? Sound feels flat? SoundBooster is a volume booster and equalizer that adds extra loudness on top of your phone's normal volume and lets you tune the sound the way you like it, through the speaker, wired headphones or Bluetooth. No root needed.

🔊 VOLUME BOOSTER
Handy for quiet music and podcasts, and works with many other audio apps. Turn the dial or pick a level, up to a 200% boost setting. This sound booster adds gain above your phone's normal maximum; how much louder it gets depends on your device and the app playing the audio.
You stay in control:
• Set your own safe limit in Settings, from 100% to 200%
• The dial changes color when you go above the normal level
• A hearing safety reminder appears before you boost past 100%
• Volume lock keeps the volume where you set it

🎚️ EQUALIZER AND BASS BOOSTER
Shape the sound with the built-in music equalizer.
• 12 presets, including Pop, Rock, Hip-Hop, Jazz, Classical and Vocal
• Bass booster for a fuller low end
• Virtualizer for a wider sound on headphones, plus reverb
• Drag the bands to make your own sound, and the app remembers it
The number of equalizer bands depends on your device.

💧 SPEAKER CLEANER
Sound muffled after a splash? The speaker cleaner plays a low tone for 20 seconds that may help move small drops of water out of the speaker grille. It comes with a countdown and simple tips, like placing the phone with the speaker facing down. It does not repair a damaged speaker or replace your phone maker's water-care advice.

🎵 MUSIC PLAYER
A simple music player for the songs saved on your phone. Browse by songs, albums and playlists, with shuffle and repeat. With optional notification access, you can also play, pause and skip tracks from other music apps on the same player bar.

📱 HOME SCREEN WIDGETS
Use the volume booster and equalizer widgets to change the boost level or switch presets without opening the app.
