1. Uninstalling it to make room hopefully for something that functions as stated.This app sucks I went for the pro version and you turn the booster up all you can hear s feedback it lasted a whole 10 min before I cancelled .WHY IS THIS APP IN the "FREE" category? I'd give it no stars if I could! If you don't purchase the bonus features, I wouldn't suggest this app.There's so much feedback can't hear nothing but screeching and cannot switch it offDON'T GET.... It asked for payment immediately for option of what it does.
2. not impressed I was listening to some people behind me playing music real loud and yelling but I couldn't hear them through the app yet I kept hearing a loud sounds that sounded like your ear does whenever you have suffered from tinnitus.
3. Also there is no notification to control the app from the background (you have to reclick the qpp icon to show it again)I should've read the reviews before purchasing this poorly executed version of an audio amplifier.
4. Unable to exit the app (No UI for exit), Doesn't have demo for bluetooth or wireless headphone recording (claiming no delay in the ads but it's hard to believe).
5. anyways not impressed with app so I go to see if I can find a better one.Does not work as advertised.
6. Recording does not work.
7. It didn't record after payment it locked the options and wanted me to pay again.
8. Stop working after a short time.The worst ever.
9. And of course next thing they're asking me to subscribe.Poorly design app on galaxy a42.
10. On top of all that he record opinion didn't work.
11. Also I only have bluetooth earbuds so no checking it out before purchasing sucks.
