Works great with Bluetooth speaker

Didnt increase volume any
Is the best it works great no problems with it all makes my phone work great sounds a lot better this is a great app you love itOK
First one that worked for me but would be nice to be able to control my phone its kind of all or nothing
It's cool but when watching a movie it won't allow me to turn it down it stays at 100.
I Give It 5 out of 5 because it does what it says does choice for yourself you won't be disappointed
Doesn't work on my Galaxy S4
It makes my volume even more louder then it was before!
This app made my music go lower when I turned it on
Make my music in my car from my device sounds good that sh*** hit
Didn't make any difference apart from boosting the volume in Norman collier like snips
Wish it could make it even louder. But so far I could hear the difference.
Does ok but can't turn down goes back to full auto.
It really helped. I have a hard time hearing people talk to me on my phone, & now I can hear them a lot better. Great so far.
It doesn't work
Finally an app that does what it says.thank you

Either too high or too low, music doesn't sound right
Don't work at all don't wast your time
I think I notice a difference in the volume. But how do you use it while listening to you tube?? I ent even know if it's on ??
