Louder: Volume Booster & EQ

Booster makes everything you listen to louder — music, videos, podcasts and games — while keeping the sound clean.

Turn the dial past 100% and Booster adds extra gain on top of your system volume using the phone's built-in audio processing. A built-in limiter keeps the signal from distorting, so you get volume, not noise.

VOLUME BOOSTER
• Boost sound beyond the system maximum
• One dial controls system volume and boost together
• Works with your favorite music, video and game apps
• Keeps boosting in the background while you listen
• Quick presets: Music, Movie, Game, Night, Bass, Max — or create your own

10-BAND EQUALIZER
• Full 31 Hz – 16 kHz range, ±12 dB per band
• 18 ready-made presets: Rock, Pop, Jazz, Hip Hop, Electronic and more
• Save and reuse your own custom curves
• Works at any volume — even with the booster off

SOUND EFFECTS
• Bass Boost for deeper lows
• Virtualizer for wider, surround-like sound
• Reverb: Room, Hall and Studio
• Left/right channel balance

MEDIA CONTROLS
• Mini player shows what's playing
• Play, pause, skip and seek without leaving the app

SMART & SAFE
• Automatic profiles per output: speaker, headphones, Bluetooth
• Sleep timer lowers the volume after a set time
• Hearing-safety warning and automatic rollback at high levels
• Fully transparent when off — your sound stays untouched

Booster is designed to be transparent: when boost and EQ are off, your audio passes through exactly as the system plays it.

Note: maximum achievable loudness depends on your device's speaker, headphones and Android version; a few devices restrict system-wide audio effects. Listening at high volume for long periods can damage your hearing — use high boost responsibly.
