About this app

Head Booster makes your phone louder with a single turn of a knob.

Is your speaker too quiet for music, movies or podcasts? Turn the big knob past 100% and Head Booster amplifies the sound beyond the system limit — up to 200% (an extra +30 dB of gain) — using Android's built-in audio processing.

HOW IT WORKS
• 0–100 % — controls the normal system media volume
• 100–200 % — keeps volume at max and adds extra amplification
• Works system-wide: music apps, video players, streaming, games and browsers

FEATURES
✔ Precision hardware-style knob — drag to exactly the level you want
✔ 5-band equalizer with system presets (Rock, Pop, Jazz, Dance...)
✔ Quick presets: OFF, 100%, 150%, MAX
✔ Media volume slider synced with your hardware volume keys
✔ Keeps boosting in the background while you use other apps — with a notification so you always stay in control
✔ Instant stop button in the notification
✔ Dark neon design with a live soundwave
✔ Light and fast — no account, no sign-up
✔ 14 languages, switchable inside the app

SAFE FOR YOUR EARS
Extra amplification can distort sound and, at very high levels, damage your hearing or small speakers. Head Booster warns you above 120% and caps the boost at a sensible +30 dB. Please use high boost levels responsibly, especially with headphones.

NOTES
• On a small number of devices the manufacturer's audio stack does not allow system-wide amplification. The app will tell you clearly if that's the case.
• Boost applies to media audio (music, video, games). Alarm and ringtone volumes are not changed.
• The app shows a small banner at the bottom of the screen.
