User Reviews
You would think for an app that you have to pay for you could at least have a back button. This app is trash. Who ever approved this ought to be fired.
It's shows in you in the app. Pretty self explanatory.
I was hoping for a useful program to examine different changes in speaker and enclosure variables. This application consistently freezes and provides frustration and no answers. Highly disappointing support for a company that clouts it over 50 years old. That is a lot of time to potentially figure things out, or not!
I didn’t realize that there haven’t been any updates in 3 years. The app doesn’t have the L7T as an option so it does me no good. What a waste.
This app is horrible. Whatever section you pick there is no back button, you need to force close the app and reopen it to pick another section. The tone generator section lists start tone, end tone and seconds so you can build your own sweep tests but you cannot change any setting except the first start tone. I can’t believe I paid $3.99 for this garbage. I bought two 12” solo baric 750w L7s and a custom mega cab ground shaker box and wanted to play with some of the options in this app but kicker obviously hasn’t tested this app out on a new iPhone 16 pro max.
When will the new Solo x be added to this? Other than that app does what it needs to
Whe i try to go to manage drives the app kicks me out the worst 3 dollars spent
No back button. Have to force close the app to go back a screen. Not worth the money.
Yall ever plan on adding some of the newer subs? Like the L7T and L7S series? Also, I’d really like to see the box builder include options for designing a downfiring enclosure. I realize that this app hasn’t been updated for 2 years at the time of this review, but hopefully yall continue to maintain it.
Garbage. Don’t waste your time and money
