What's New in Equalizer Fx

4.8.3

December 19, 2025

[New] • Now you can choose whether DRM-protected songs appear in your library or not using the new control in Settings. [Optimized] • You can now clearly identify DRM-protected songs. Encrypted songs now display a visible DRM tag, making it easy to recognize at a glance. • Now, when a DRM-protected song is played, the app displays a “DRM-protected” message along with details about the limitations on applying music effects to these songs. [Fixes] • Fixed an issue where the playback order resets to the first track instead of following the correct queue. • Bug fixes and performance improvements.

Useless

Useless app, dont bother

Don’t waste your time trust me.

Garbage apps

Complete waste.

Don’t even bother everything is locked behind a paywall and you have zero control over music and have to buy every song you want to control and also pay for a monthly sub. Just look somewhere else
MLMr. Lean_master4200

Good but a bit inconvenient.

Please make it so that when turning the EQ off for a custom EQ the bands don’t lower in volume. It’s very inconvenient when switching the EQ on and off to check what sounds good when adjusted. Other than that it’s a nice app. I use it for checking my music on my AirPods when mastering it to be published.

Clunky interface. Lacks simplicity.

I found it an awkward interface and too many steps to integrate with my music libraries. Great idea. Maybe future versions will make it easier to fall in love. I do very much appreciate the feedback I got from the developer and have updated my review accordingly.

FAQ

What does the Equalizer Fx app do?

This app enhances your music listening experience by providing a powerful 7-band equalizer and bass booster. It allows you to modify sound effects using pre-set amplifiers or by creating your own custom presets. You can also enjoy background music playback and stream radio stations.

What are the key features of Equalizer Fx?

Key features include powerful bass-boosting effects, a 7-band EQ with DJ transitions, elegant music visualizers, the ability to create custom equalizer presets, background music playback, and radio streaming. It also offers a variety of pre-set equalizer options like Acoustic, Bass Booster, Classical, Hip Hop, and Rock.

How much does Equalizer Fx cost?

The app is free to download, but requires an auto-renewing subscription for full functionality. Subscriptions are available on a monthly or yearly basis. A free trial period is offered, which automatically renews to a paid subscription unless canceled at least 24 hours before the end of the trial.

What devices is Equalizer Fx compatible with?

The app is designed for iPhone and iPad devices. It requires unencrypted raw audio data to apply effects, meaning it cannot apply equalizer, bass boost, or volume boost to DRM-protected music such as Apple Music tracks unless the songs have been purchased and owned from iTunes.

Can I use this app with Apple Music?

You cannot apply equalizer, bass boost, or volume boost to DRM-protected music, which includes Apple Music tracks. The app needs unencrypted raw audio data to function. However, if you have purchased and own songs from iTunes, you can use the app with those tracks.
