### 1/5 — Do not purchase

*2024-04-12, version 5.8.0*

Nice visuals but about 3 seconds of latency, so not a real time visualizer. Not useful

### 1/5 — Wrong spell.

*2024-01-13, version 5.8.0*

I’m confused why this message came up “Error. Please try again lator.” WHAT DOES THIS MEAN “LATOR?!?” This is something a app w/ wrong spell and NO MUSIC I CAN CHOOSE FROM PHOTOS!

### 1/5 — Slow

*2023-07-30, version 5.8.0*

This app is WAY too slow. I can’t do anything before waiting 5 minutes for anything to load when I tap something. Fix this.

### 2/5 — SMH

*2023-06-08, version 5.8.0*

I really hate this new update. I can’t even add my own music from my files like I use to. A waste of 1.99 the first time I got it. 👎🏾👎🏾👎🏾👎🏾

### 1/5 — Piece of crap.

*2023-04-16, version 5.8.0*

I don’t know why this is sohard. Just want to see visualizations or ALL of my music. Three apps and no luck. This just locks up if you look at it hard…

### 1/5 — Garbage

*2023-03-02, version 5.8.0*

Probably due to age but it froze within a minute multiple attempts on my iPad Pro. Doesn’t work.

### 5/5 — Spectrum Music Visualizer

*2022-06-23, version 5.8.0*

Amazing app. Finally it Came out. Only inconvenience is that only Songs Bought from iTunes Store play and Missing a Visualizer for Apple Watches.
