  1. 5/5Version 2.4.5

    I was in need of a music app to replace an app that was no longer being maintained or supported. The replacement app must satisfy three requirements: 1. Provide a clean, simple interface to a large iPod music library. 2. Include an integrated equalizer that allows for fine tuning music to my preferences. Providing an equalizer that restricts EQ settings to a limited set of presets is not sufficient. 3. The app must NOT be SUBSCRIPTION based. Equalizer Pro + appeared to satisfy all my requirements so I invested $3 and downloaded version 2.4.3 of the app. Initially, I was disappointed in the functionality and performance of the app, specifically the user interface, the extraordinary amount of time it took to load a relatively large iPod library (800 albums, 12,000 songs), no ability to display and select albums by ‘Album Artist’, and problems adding songs to playlists from multiple albums and lists. In addition, I noticed that occasionally all songs from a selected album were not included in the playlist and songs in the playlist were sometimes skipped over and not played. ‘Recent’ user reviews either gave the app 5 stars or 1 star. There were very few average ratings. I also noticed that I was experiencing many of the same issues and problems that were described in the 1-star reviews. If I had read the ‘Recent’ reviews prior to purchasing the app, I probably would not have purchased it. I contacted the developer who was VERY responsive, receptive and appreciative of any comments and suggestions. He worked closely with me to address the problems and to implement new functionality where needed. Version 2.4.5 provides a major improvement to the functionality and usability of the app and integrates very nicely with large iPod libraries. I strongly encourage anyone who was dissatisfied with an earlier version of the app to download this version and give it another try. I’m positive you will find the app to be much more reliable, usable, efficient and intuitive. If you are uncertain about purchasing the app, I highly recommend that you give it a try. The app is very much worth the price for the functionality, performance and sound quality it provides. You will not regret it.

  2. 5/5I finally found THE one

    This has everything. Reads my iTunes library and gets the correct album covers. You can set a lot of gestures as YOU like them, like volume up and down, set how far ff and rewind, 20 or 15 or 60 seconds or whatever, great equalizer. Really customizable. I have downloaded a lot and paid for a lot but wow this is wonderful! I tried to give a review from the app and iTunes told me this is not available in my country (?)

  3. 5/5Overall great app

    Great app for fine tuning sound in car audio or for extra sound boost on iPhone. If there's anything that I had to gripe about, it would be only two things. First.. no screen rotation. App should rotate when the phone is rotated, second.. the little blue dots used to make fine tuning eq adjustments can be frustrating for someone with wide thumbs, especially the ones on the edge of the screen. Besides that... worth the download. I have a Sony Xplode radio in my truck, which already has multiple sound adjustments, this app helps fine tune even further, ever track sounds amazing, from metal to country to rap, all sound perfect for my taste.

  4. 4/5Sounds great

    I use it daily when I Bluetooth my iPhone 10 to my BMW X5 SUV. My IPhone 10 pairs up fast and the Equalizer Pro APP is ready to go-I leave the app open. SOUNDS better than the proprietary music app that comes with IPhone 10’s operating system. You have to experiment and experience the nuances in this powerful app until you find your sweet spot. If you don’t like tinkering with apps just play Equalizer Pro as is...you will definitely enjoying it. It plays on my Denon receiver at home and the music coming out of my speakers sound rich and powerful.

  5. 2/5Had to buy this app again. Not happy.

    I have used this app for some years but when I went to update it I wasn’t able to because it said it was no longer in the App Store. I had the option to delete or keep. I had paid for the full version so I kept it. Checked out the App Store and it was still there. In order to get it to work, I had to buy it again. Not happy that I’ve had to pay twice. I don’t know if this is the fault of the store or the developers but because I like the app I bought it again. Please fix this bug.
