*2024-11-27*

Disappointed

### 1/5 — Drivel

*2024-07-22, version 3.5.4*

There’s a half decent little unit here but ads pop up making it unplayable. What was the point?

### 1/5 — Don't! don't! Lost the respect and admiration for Apple.

*2024-05-21*

Totally unusable product! you'd be repenting your decision later after clicking the purchase button. hope it'd save somebody, and don't have to go through this nightmare of an app. Worthless waste of an app from a very genius developer. I wish they Could’ve Learned from Audiothing, Bram Bos, OSC, 4pockets, Bleass, these giants. It’ll always be a wastage of an app, save your bucks!

What are you try to become apple, The most materialistic lustful corporation, Totally ravaged the dream Steve Jobsstarted Apple with.

### 2/5 — Don't! don't!
