About this app

🔥YES this is the NEW app you were looking for🔥
It sounds like NO other!

It’s not just an equalizer, a regular bass booster, or a low-volume amplifier.

It makes the bass bounce like no other app for Android.

This is what you need if you crave those punchy low-ends, with kicks and snares that pop.

It makes the music sound more beautiful and EXCITING.

This is what you need if you love having those goosebumps and chills when you listen to emotional or energetic songs.

It has many different facets and mixes them in the most user-friendly way. It allows you to control how your speakers or headphones sound and deliver your favorite songs.


It's not really an equalizer audio effect actually: it's better.
It changes the audio frequency dynamics.


You clearly get more bass but without undermining other frequencies and ending with a frustrating heavy or hollow muffled sound.
You get that subwoofer effect even with lighter gears, thanks to the deep boosted bass.
You can really bring the bass to the front, make it sound big, punchy, and bouncy.
You will feel the bass in your chest.
All of that without degrading the stereo image.


It allows getting a louder sound level without compromising the clarity with excessive distortion.
Fix problems of too low volume on your smartphone's built-in speakers.
Increase the volume for any situation: outdoors, in your car, at home, in parties, in dancing parties, in your dance school or dance studio, in nightclubs, in bars, etc.

Fantastic! I've written this two or three times, and I keep thinking of more to say. Google needs to give us more space, LOL, so I'll just say this. Get the app. It's not like other sound boost apps. It is ultimately customizable, and you can save your settings as presets. Changing presets changes volume, so adjust it to a level that allows you to make a good decision about it. Change any to tweak presets and save as a new preset. It's like getting a new car stereo or phone.

This is the best equalizer that I have ever used and downloaded (and I have used and downloaded quite a few)! The reviews are completely accurate about this app. FINALLY, an equalizer app that actually works! I really like playing around with all of the settings and finding different combinations of settings to make the sound that I want in that moment. It's really user friendly, so even if you don't know what you're doing, you will be able to still use it and enhance your music. ❤️

Way way way better then other equalizer apps I've tried. Bass boost doesn't muffle the music, like so many other apps. Music played through my headphones seems more separated. Like I can hear music notes I didn't notice before when playing songs I've listened to 100 times. Highly recommend this app, if your looking for an EQ with bass boost and gain boost. 5 star app for sure.
