Handy sound verstärker app

I'm typically skeptical of apps like these because so many do nothing that they claim. Was actually pleasantly surprised by this. Definitely helped with the volume and all the equalizers worked when implemented. No complaints - did what it said it would. EDIT: As great as this was, every i will find a synonym for "giebel": & again a strange foreign noise came through - its really weird & disturbing, sounds like something from a horror film. Really hard to describe when it happens, but has meant I can no longer use this sadly.

Galaxy Note 20 5G Ultra. APP WORKS! The presets are really good. The boost drops every few songs but sometimes kicks back in without having to turn off/on or manually adjust. The edge lighting is cool! The ads... Forget about it! Too many!.. BUT for a FREE app that rocks I understand the need to keep the developers creating and making it even better. Overall, I liked it so much...I paid the lifetime purchase to remove the adds!!!🎉🎊 Hope updates are included for life, as well.

Love the app. Works even when playing music from YouTube(instead of closing) which is PERFECT, as I have been trying to find a way to have the music from YouTube boosted. Having said that, it's VERY unfortunate that the frequency doesn't go from 20hz to 20khz. Instead it starts at 60hz (JUST above the "sweet spot") and ends at 14khz. Also, it would be VERY VERY nice to have it not use up so much of the CPU. I get critical messages saying it's above 25%. I have a Note 8, so it SHOULD hold well.
