## Most critical reviews (5 lowest-rated)

### 1/5 — unresponsive and lag

*2025-08-18*

space synthesizer is the most unresponsive and laggy synth I've ever downloaded on the app store. keys take a whole second before they realize they've been pressed. and the built in beats are all over the place.

### 1/5 — App has No sound.

*2025-08-05*

Worth every penny.

**Developer response:** Hey, sorry you aren't hearing audio, the likely reason is your phone is in silent mode.

### 1/5 — Seriously?

*2024-04-18*

Bah!
