## What is Equalizer?

"... the sound quality blew us away."- Gearburn.com
Music player with the most powerful and acurate equalizer in the app store as well as the most advanced playlist controls.

+ Play music directly from your Music Library including podcasts and music video (audio only)
+ Adjust the powerful parametric equalizer by moving the seven control points or type in the values directly.
+ Adjust the EQ curve for your left and right ear separately (now extends from -30 to + 30 dB. Use the StereoEQ setting for that)
+ Select from over 10 presets or save your own. You can even share them via email and import presets from other people via email.
+ Full background support including remote control (from docks, headsets, car stereos)
+ Visualize the music with the spectrum analyzer.
+ Use AirPlay to listen on your AppleTV, or your Bluetooth headsets and even a dock. 
+ Use the pre-amp slider to adjust the overall boost or cut. Make sure to turn the slider down if you experience distortion. Use the auto-normalizer function to prevent clipping automatically and have the best dynamic range possible with your eq curve. (on/off in settings)
+ Curve screen: curve redraws as controllers are dragged. Pinch to modify Q. Three stage clipping signal on preamp slider. Keyboard entry for pre-amp. Twitter/Facebook/Weibo integration to share your current EQ curve. Bypass.
+ Crossfade between songs. Make sure to stop the music before changing the crossfade time slider.
+ Now playing screen includes repeat (all, single no repeat) button and shuffles like the music app. Improved stability of on the fly modifications of the playlist. Add more songs to the playlist at any time. Sort playlist alphabetically.
+ Music selection is very similar to default music app.
+ Turn landscape to display the frequency analyzer. 
+ Built in sleep timer to stop Equalizer after a certain period if time. 
+ Crossfeed option to blend audio between channels
+ Apple Watch support for eq curve selection incl. complications

KNOWN ISSUES:
No known issues. please contact support if you have any problems.

COPY-PROTECTED MUSIC:
Equalizer will not play copy-protected (DRM). You need to convert DRM songs. Apple Music Streaming uses copy-protected songs.

iCLOUD:
Only the Apple Music app can manage songs in iCloud (iTunes Match). You will need to make sure the songs are downloaded to your device to listen and enhance them via Equalizer. If you want to stream and eq your music, you can try our other app: CloudEQ. It allows you to stream and eq music from SoundCloud and your Dropbox account without the need for storage on your device.

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

### 5/5 — Avid Listener

*2026-08-09, version 5.20*

Perfection !

### 5/5 — Outstanding!

*2026-03-25, version 5.20*

This app is outstanding but the auto normalizer only works occasionally lately in iOS 26.4. Can you please fix this outstanding feature? Thank you.

### 4/5 — Best Eq, everything I was looking for.

*2026-02-15, version 5.20*

This equalizer kick but! I can dial in exactly where I want my bass boost frequency, the amount of boost, and best of all the width of the Q ( how quickly the curve tapers off) it’s awesome. 

This was the biggest problem of listening to music on an iPhone. Apple’s E.Q. Is horrible for user control. Especially for anyone who loves a parametric Equalizer. Since apples iPhone E. G. So far versions of iOS you can’t select the frequency only presets curve assumptions of what the user might like. 

This equalizer fixes all of that.

### 5/5 — Update

*2026-02-14, version 5.20*

Update please 2026

### 4/5 — Great Amazing Improved Sound

*2025-10-09, version 5.18*

Update: 9/22/17 - App keeps crashing after iOS 11 update The ability to sort albums by date they were added would be a handy addition. Love the product otherwise

Update: 10/6/23 - No longer working properly in iOS 17….scroll bar progress stuck in one place although music still playing. Buffering doesn’t adjust properly anymore

Update: 9/18/24 - Still doesn’t work properly. Very unfortunate. Hopefully updating the app to iOS 18 will help

Update: 10/9/25 - Issue I had was due to cross feed or cross fade. Don’t use them or set to default value. Worked mostly fine since

### 5/5 — Best EQ for audiophile gear

*2025-09-26, version 5.18*

Equalizer is indispensable for classical and opera on audiophile equipment. 
Very impressed with its ease of use and wide range of EQ and soundstage options. Surprised it’s not more expensive.

### 1/5 — Irreführend

*2025-07-27*

Beim Überfliegen der Beschreibung kein Hinweis, dass Spotify & Co. nicht funktionieren. Fühlt sich wie rausgeschmissenes Geld an – hätte ich das gewusst, hätte ich nicht gekauft.

### 3/5 — Stability problems

*2025-04-24, version 5.18*

With the update to 18.4 the app crashes significantly less often but the problems are still there - original review - The EQ sounds amazing (easy to use curve editor), but the player often crashes at the end of a playlist, or playback may freeze at the end of a track. Installed on iOS 18.3

### 1/5 — Lies

*2025-04-21, version 5.18*

They lie when they say you can play music directly from the Apple Music player. Nothing plays. Very deceptive developer.

### 3/5 — Hobbles all DRM songs

*2025-02-15, version 5.18*
