About this app

Sound booster, volume booster, equalizer and bass boost — with honest decibels. No fake "200%" claims, just real dB.

VolumeBooster+ amplifies your phone's sound in true dB (0 to +15 dB) with built-in safety zones based on WHO hearing-loss guidelines. You see exactly when the volume enters Caution (+6dB) or Danger (+10dB) — no marketing tricks, just your ears in control.

🎧 HONEST DECIBELS — NO FAKE BOOST CLAIMS

Other apps advertise "200%" or "300%" volume that you cannot verify by ear. VolumeBooster+ uses real dB measurements and a unique "Honest Mode" — press and hold the compare button to instantly hear the original audio. Verify the boost is real with your own ears.

❤️ HEARING SAFETY FIRST

The WHO recommends limiting exposure above 85 dB to under 30 minutes per day. VolumeBooster+ tracks your listening sessions and reminds you to rest. Quiet Hours auto-cap headphone gain during sleep. Set separate gain limits for headphones and speakers — lower for ears, full power for room speakers. The optional Hearing Safe Mode (Limiter) clamps audio peaks on Android 9+.

🎯 AUTOEQ — YOUR HEADPHONE'S TRUE SOUND

Most consumer headphones are not tonally flat. AutoEQ uses community-measured frequency response data to correct your specific headphone's signature. Search 2,000+ profiles (Sennheiser, Sony, AirPods, Beyerdynamic, AKG, Audeze, HiFiMAN, Moondrop and more) and apply the correction with one tap.

🩺 PERSONAL HEARING TEST

Take a 1-minute test at 5 frequency bands per ear and get a personalized EQ matched to your hearing. Re-test every 6 months to keep it accurate. Export your audiogram as PDF.

🌙 TINNITUS RELIEF

Mask ringing in the ears with calming colored noise: Pink (recommended), Brown (soothing), or White (bright). Use Pitch Matching to find the exact frequency of your tinnitus.
