About this app

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

It’s only the best equalizer, regular bass booster, or 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.
We are confident you won't find a better sound booster sound-quality-wise.


It's the only Music Beautifier on the market right now, the original one.
Get clearer and more natural vocals or speech by exciting the voice.
Make singers more present and feel like they are really with you.
Enhance the beauty and the energy of the music with the app's audio exciter abilities.
Subtly reveal more of the reverb already mixed within the song; sublime it.
Remove that veil on the sound preventing you from hearing every instrument more clearly.
Improve sound quality.

I had to give 5 stars not only for being the best booster I've found so far that actually does as it says, but also it's very user friendly to even the casual music lover. Also, there's a feature that I'm totally in love with that I've not seen ANY other apps offer: the ability to create a custom audio preset for each of your audio devices (Bluetooth speakers, headphones, earbuds, ECT). No more having to adjust sound quality every time you switch from one to the other! 💕 in love 💕

When it worked it was really nice. Android auto just doesn't produce sound loud enough. It's quieter than everything else and makes it so even at max volume you're not getting enough. Add am extra ~2-3 dB here and you're good to go. Except, the app hasn't been doing anything for me recently. No boost. Went to check permissions today and couldn't change anything. Take that with a grain of salt though, I'm running a custom ROM. That usually means you have increased permissions for apps...

really great app to clean up sound. can use while listening from separate apps so doesn't need to have the sound you're listening to downloaded to phone. can watch 30 second ads to unlock different sound presets, but have the option from the start to customizer your own sound presets and you can save them too, though they do have some good presets I can't seem to get my finger on through my own efforts. ads are easy to deal w & have a instant exit button.
