From the reviews: EXCELLENT PROGRAM 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_ *** LOVE IT 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 http://www.audioforge.ca and we will explain how things work, until you can use all the features of the app to the fullest. Thank you

Verdict

The call

The clearest difference is price: Equalizer Fx at Free against Equalizer's $3.99. Equalizer Fx also leads on rating (4.2 vs 3.3) and ratings volume (28K vs 138). Equalizer's advantage is review sentiment (61% vs 19%) and in-app purchases (none vs 10). On device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Equalizer Fx holds the better App Store score, 4.2 against 3.3. That said, the two scores are not equally well evidenced: Equalizer Fx has 28K ratings behind it against 138, so its average is the more settled of the two. Written reviews complicate that: 61% of Equalizer's written reviews are positive against 19% of Equalizer Fx's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Equalizer ships an update every 2 months, Equalizer Fx every 3 weeks. The most recent releases landed on September 24, 2026 and September 25, 2026 respectively.
