Please have a look at our dedicated online radio app: RadEQ - Equalizer for streaming online Radio

Equalizer will not play DRM or iTunes Match music in iCloud. You need to convert DRM and download iCloud songs.

Equalizer is not providing the functionality for rendering your eq curve to the song. However, our other app: Remaster does!

From the reviews:

I connect my iphone 4 to a car audio system, with the application the music began to sound incomparably better ....
A little clear interface, but to understand it and understand need no more than 5-10 minutes. -- P_S_B_
This is the EQ I have been looking for, and because of bad ratings I almost passed on it! I consider myself an aspiring audiophile and have the equipment -- Klipsch, Sunfire, Nottingham, Denon, Paradigim, etc. -- (and debt) to back it up. This EQ performs flawlessly and is very easy to use. It enhanced my music dramatically. Yes, dramatically! Just make sure you are running the recommended IOS, as the developer suggests. -- J. Paul DiMaggio

PLEASE if you have concerns or encounter problems with the app: post on and we will explain how things work, until you can use all the features of the app to the fullest. Thank you

Customer Reviews

Ignore the haters...

...Equalizer is a great app.

The dynamic range on Equalizer is, imho, superior to other players that I've tried. Equalizer's also easy to use, from my experience. Nothing's too complex, especially if you're familiar with an in-home stereo system. Easy peazy.

The shuffle issue that people are complaining about is a nonissue if you take a half moment and turn the shuffle setting OFF! Duh!

My one gripe is the fact the Equalizer can't handle some of the DRM encoding on some purchases from the Apple Store. In a nutshell, it'll grey out the songs it can't/won't play, and you'll have to open a different app that can play 'em. It's a stinky setup that I wish would change, but it's worth the trade off for the better sound on the rest of one's music library.

The Winner is...

I can’t tell you what a great “equalizer” app this is and I’ve tried quite a few. Not only is it my favorite by far but the customer service is personalized and top notch. It’s like having your own custom programmer should one require help or troubleshooting. Equalizer is my go to daily equalizer app for the ultimate audio device experience.

Long term user

As a long term user, I am always exited to see that this app still gets updated, after so many years.
Sometimes new feature, sometime bug fixes, small changes, big changes, good and bad.

But what counts for me is knowing that they care about their app and how good music sounds.
