### 5/5 — ($.Dope.$)

*2026-05-31, version 1.88*

($.Cool Application.$)

### 1/5 — Nevermind.

*2026-05-17, version 1.88*

The 10 band equalizer is not free.

### 5/5 — Nostalgia rhythm

*2026-05-14, version 1.87*

The base boost on this takes me back. Loving it

### 5/5 — Good truly free music player!

*2026-04-18, version 1.87*

First thing this app does after downloading is display a subscription screen. You can do nothing else until you subscribe. Does offer a three-day 'free' trial, but like always you have to enter all your credit card info first and then cancel before the three days are up. Program might be worth it, but it should state up front that's it's a paid app. 

********** Update 1/21/23 
So I got an email telling me that the app is now free. Yeah, the app itself is now free, but it comes with no equalizer or bass booster, those cost extra. Still not interested.. 

********** UPDATE 2/20/23 Ok, so now the app really is free, including the equalizer and bass booster functions. It doesn't seem to be an add-on to Music Player X, just a separate independent player. A little confusing, but it works.

********** UPDATE 4/2/26
The app costs $15 per year to use after a free three-day trial. I think it's worth it. All I wanted was a multi-band equalizer for Apple Music and CarPlay, and this is the closest I've found. The controls are straight-forward and easy to use, the equalizer is just a button away from its main screen and can save three presets, and most importantly, IT SUPPORTS APPLE CARPLAY!! You can actually add the app to your CarPlay screen!

### 5/5 — Equalizer wasn’t free at first but they will update the app soon.

*2026-03-26*

You had to pay for the equalizer. 

I have updated my review after the developer said that the EQ will be free next update.

**Developer response:** On the next update EQ will be free. Thanks for your feedback. Update now available!

### 1/5 — Equalizer isn’t free

*2026-02-07, version 1.84*

You have to pay for the equalizer.

### 5/5 — We

*2025-10-28, version 1.84*

Works good for what it’s made for

### 5/5 — Different types of quality

*2025-09-27*

At first it was difficult to understand why it had all these problems and why they had to be fixed so afterwards we could not find the solution to transfer a playlists from their original platform to give us instructions on how to transfer things from theirsS to our IPHONE system but it is very good!!!!.,

### 5/5 — Add - On Feature

*2025-07-22, version 1.83*

I am enjoying the app…. But can I get my money’s worth by you adding a CONTROL UNIT FOR THE SPEED AND THE PITCH? ( ex. 0.1, 0.2 ) greatly appreciated.
