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 rating: Equalizer Pro + at 4.2 against Equalizer's 3.3. Equalizer Pro + also leads on update cadence (fortnightly vs every 2 months) and ratings volume (557 vs 138). Equalizer's advantage is review sentiment (61% vs 47%) and price ($3.99 vs $4.99). On ads, in-app purchases, monetization model and device support there is nothing between them.
