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.

Boost, Tune and Extras are three tabs under the master switch, so nothing is more than one tap away.

Bass that you feel
• A dedicated bass strength control, from a gentle lift to a hard punch
• 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 with the gain in dB above each one, and a live curve of what you set
• 15 built-in curves that behave the same on every device, plus your device's presets
• Save your own curves under your own names and switch between them in one tap

Loudness boost with the real number on screen
• Up to +15 dB through Android's Loudness Enhancer, with the exact gain shown in dB
• Safety zones warn you before levels that can distort your speaker or hurt your ears
• Soft start eases the boost in from every switch, widget and routine

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, and reverb from a small room to a concert hall

Sleep timer and output profiles
• The sleep timer fades the volume down, 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

Volume scenes and per-app level
• Save media, ringtone, notification, alarm and call volume as a scene and switch in one tap, with Undo
• Link a scene to your headphones or car Bluetooth so it applies when they connect
• Give a supported music player its own level, always within the safe listening cap
• 3 scenes, 1 linked device and 1 player level are free; more with Premium or Boost Points

Gentler on your speaker
• Speaker guard: on the phone speaker at high boost it eases the deep bass the speaker can't play and keeps a peak limiter on. Turn it off in Settings
• When headphones connect, media volume rises gently over 2 seconds

Quick controls
• Previous, play/pause and next under the boost slider and on the small widget
• Home-screen widget, Quick Settings tile and notification controls
• Light, dark and true-black AMOLED themes

Pro bass tools
• Bass Tuner: a subwoofer-style low shelf with its own peak limiter (Premium or a 24-hour unlock)
• Low-volume bass compensation brings back the lows your ears lose at quiet levels

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.

The app shows where its effects land: players that announce their audio session get them directly, the rest via the global session.

All audio processing happens on your device. Nothing is recorded and no audio is ever uploaded. Firebase Analytics and Crashlytics are optional in Settings.

No account. No sign-up.

Note: some manufacturers' own audio processing limits certain effects. The app tells you, and the rest keep working.

Fixed a rare crash on launch right after an app update. Smoother and more stable overall.
