Not what it used to be

This app used to be completely free and very good until the creators got greedy and locked some of the features and they have constantly gotten more expensive. I would have been fine with the app until they took away Bluetooth support as well as many other features. The price for the full app is now $10 which I would never pay for in an app that was completely free at one point.

Developer Response ,

We apologize for the inconvenience.
Good work usually requires some time, so there will be several updates. We keep working on the app to make it better.

No Bluetooth

Test tones will not play through Bluetooth. How am I expected to use this for subwoofer placement? You need to have the phone in your listening position to accurately measure your sub output. This means you need to be able to connect to your receiver wirelessly! I want my $10 back!

Great for car Subwoofer testing

I love playing with this app with my Subwoofers in my car. It works perfectly for having fun with the bass and to surprise people with the power it puts out.
