Love the idea and sound it gives my phone. The biggest issue is that YOU CANNOT SAVE PREAMP SETTINGS. When the phone powers down or reboots, you must reset all preamp settings again... and again..... and again. The preamp settings are not kept. They should be. No options to keep them either. When this changes, and works on my S24 Ultra, you will get 5 stars then. Until then, only 2.

I love this app it doubles (more than that) the volume of the sound output of my mobile device and you can use the equalizer to tailor the sound to your preference. I would love to see this app on a chrome cast with google tv to enhance the sound and singing voice when having a karaoke with friends. Need an app like this to enhance my not so good singing voice but still love to sing.

It DOES work, and it really helps with how much bass my headphones have. My issue with this app that makes it a 3 star, is that the moment one piece of audio ends, it immediately reverts to normal levels, and you have to reactivate the equalizer. As you can imagine, this is a giant pain in the ass when listening to music, needing to reset after every single song. It's fine with audiobooks, movies, and the like, though.
