### 1/5 — Still Broken

*2025-01-25*

Recent 1.0.8 version did not fix the app from the launch issue in version 1.0.7. The app will not launch on version 1.0.7 or 1.0.8. I'm running macOS 10.15.7. The Mac App Store shows updates available. New updates install. But, this issue persists. Please remedy. Thank you.

### 4/5 — Great app

### 1/5 — Terrible

*2024-10-30*

I wanted to convert music to 528hz, its in the list but you cannot select it. This app doesn't even deserve a simgle star. Refund please

### 5/5 — Positive Review & Share!

*2024-09-18*

Hello.  As a lifetime musician and producer, I've been very pleased with your app for the cost.  Some songs don't always convert perfectly but it seems logical that's just a natural consequence of trying to alter a track from it's original frequencies and all of the EQs/etc that were fine-tuned in the studio.  Thanks also for the added option of converting to other frequencies besides 432hz, that is also a huge plus to me for experimenting.  I just shared a detailed review and endorsement of this app to hundreds of others on my Telegram channel @MattSavinaMusic.  I'm also using the app almost daily to convert some songs that I post on Rumble and YouTube @MattSavina. THANKS!

### 4/5 — Unable to convert music to 528hz

### 1/5 — Disappointed
