Bass Booster & Equalizer

Bass Booster & Equalizer gives your phone deeper bass, a cleaner curve and more loudness - using Android's own audio engine, and telling you exactly what it is doing.

Three pages, one thumb. Boost, Tune and Extras sit on a bar along the bottom of the screen, where your thumb already is, and the master switch stays pinned above them. Nothing is more than one tap away.

WHAT IT DOES

Bass that you feel
• A dedicated bass strength control, from a gentle lift to a hard punch
• Works on the speaker, on wired headphones and over Bluetooth
• Pair it with the Bass sound mode for a curve tuned around the low end

A 5-band equalizer you can actually read
• Vertical sliders for lows, mids and highs, with the gain in dB above each one
• A live curve drawn from what you set - the shape you asked for, in one glance
• 15 built-in curves that behave the same on every device, plus the presets your own device ships with
• Save your own curves under your own names and switch between them in one tap

Loudness boost with the real number on screen
• Raises media loudness by up to +15 dB through Android's Loudness Enhancer
• The exact gain is printed next to the slider in dB, not a made-up percentage
• Safety zones warn you before levels that can distort your speaker or hurt your ears
• Soft start eases the boost in over a second instead of slamming it on

Sound modes for the moment
• Flat, Music, Bass, Vocal, Movie, Game, Outdoor and Night
• One tap sets the equalizer, bass, virtualizer and reverb together
• Touch any slider and the mode steps aside - your own tuning always wins

Virtualizer and reverb
• A wider stereo image on headphones
• Reverb from a small room to a concert hall, for films and live recordings

Sleep timer and output profiles
• The sleep timer fades the volume down over ten seconds, then switches the effects off
• Speaker, wired headphones and Bluetooth each remember their own preset, boost level and volume
• Plug in your headphones and their profile applies by itself

Quick controls
• A home-screen widget and a Quick Settings tile for a one-tap boost
• Controls in the notification, so you can adjust without opening the app
• Light, dark and true-black AMOLED themes

HONEST ABOUT ITS LIMITS

This app uses only the official Android audio effects. It cannot push your hardware past its physical limits, and it does not claim a boost percentage that no phone could deliver.

Where the effects land is explained inside the app: players that announce their own audio session get the effects applied directly, and everything else goes through the global session. The app says which is which instead of promising it works with every app on your phone.

All audio processing happens on your device. Nothing is recorded and no audio is ever uploaded. The app uses Firebase Analytics and Crashlytics to see which features get used and to catch crashes - you can switch that off in Settings.

No account. No sign-up. Free users see Unity Ads; Premium removes full-screen ads.

Note: a few manufacturers run their own audio processing that limits some of these effects. When that happens the app tells you, and the remaining effects keep working.
