I just wanted a SPL meter to measure subwoofer output. This thing is useless in that regards. If you want to see endless ads, then its perfect for you.

I downloaded this along with a few other apps with the objective of playing specific frequencies for my car audio system so i could better tune my amps. This app is garbage and throws “buy our app for 20$” in your face anytime you try to check out anything on the app. Its literally unusable. Do not support this company. In the end I ended up downloading “f generator” which worked without ads and “spectrum” which has ads to buy but only after you change the settings 10 or so times, way more reasonable...

I just wanted to make my headphones shake because of bass but there has been a wall of money in my way of doing that! Please fix this within the week that I have before I report this app for false advertising!

What was once an excellent, free app to use has been absolutely crippled by the developers. Nearly everything has been locked behind a pay wall and even the “free” ability has a noticeable amount of hiss. I made the mistake of updating the app, which immediately made this a perfect candidate to free up some space on my phone. $10 for something that produces hiss? No thanks. Previous review below: 5 stars: This is an excellent application for adjusting amps, subs and low-frequency speakers as it produces a stable, accurate frequency between 10Hz and 250Hz. While the coarse and fine adjustment knobs are a little oversensitive on my small iPhone with my too big fingers, the ability to type in a specific frequency more than makes up for it. The ability to select different waves of Sine, Triangle, Square and Saw-Tooth profiles will definitely help in box building.

It works so its good

Couldn’t do anything basically except to pay 9.99$ for it

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!

You can swipe up to exit app. You have to voice open another app to exit. Ugh!

Everything was great until when I tuned the knob when the sound was playing it popped a lot. That’s not good

Just awesome

Still not free 😒talking bout' $9.99 for full additional features!!😕 Really?? Also get rid of all Ads!! Please?!?!

Don’t get this

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.

Is the app support working because I accidentally purchased the $10 add free and tried emailing you guys but it’s said email not found. I just want a refund.

Another Click Bate useless app that only wants to sell you on other apps. I don’t know how well it works because the app never got a chance to work with all the adds and games that popped up before it trying to get me to buy them too

I was charged 7.99 after downloading this app. I want my money back ASAP. Answer me!!!!

Unsuccessful they ask for buy everything

Do not get app you revive adds after every click

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.

Didn’t work

Ads pop up from every where making this app totally unusable. Don’t waste your time... read th reviews and move on.

Never finished using before uninstalling. Same ad pops up each time a button or feature is activated. The ad pop up rate and the length is ridiculous.

Way to many ads

The app is awesome the test tracks are very good but it’s insane and very frustrating how many adds there are. If it weren’t for the adds the app would be 10/10 in my book

Too many ads to even play the darn game!!

Makes the app not useable..

Everyone can attempt to use this like a normal app, unfortunately there are just too many ads to even try to properly use this app.

There's one ad when you start up the app that you have to wait a long time before using. Then after that ad is finished there's a gaming app ad where you also have to wait a long time before using. Plus additional ads within the app. Totally invasive, intrusive and I acceptable. Uninstalled.

Anytime you try to change the sound wave or perform any function inside of the application, and ad randomly appears for at least five seconds.

This app is junk !!! All it does is open and show adds then shuts down !!! Garbage app .

App keeps crashing and never started. Many issues have to be addressed
