It’s great

It’s great but how do you change the tempo because I can only change the pitch and it’s annoying that I can’t change the tempo

Eq works great

Why do apps ask you to rate them right after you get them? Can I use it first? I will say as of right now, I set up the 8 band eq and it has vastly improved the sound of my aftermarket 6-speaker system! But I want to have a chance to see the apps other feature, as well as see if I can save different settings, and see if it is user friendly. I used to have an Alpine app called Tuneit that I loved! My favorite feature was the capability to change the sounds of the subwoofers only. It had low bass, mid bass, punch and a few others and that was great! That is an app I would pay for! But that’s another thing, do I want to pay monthly or weekly for an equalizer when I can just go out and buy one for $40-80 bucks?

Terrible App

I normally don’t write reviews, this app is a complete scam. While the actual equalizer and stuff is great, do not spend your money. I did the free trial, every time i uploaded music from my iPhone the app would crash and “Not Work”. I use parenthesis because this app is designed to make you spend money. You can’t upload your own music, nor can you use apple music. I have apple music and have for months, it made me purchase songs to listen to what i want. Just a complete scam for money.
