### 5/5 — Solid App + Great Customization Options

*2026-05-27*

Stumbled across this app while researching audio therapy and was genuinely impressed. The sound quality and customization options are excellent, and the interface is clean and easy to navigate. Great for relaxation, focus, meditation, and winding down after a long day. You can tell a lot of thought went into the experience. Definitely worth checking out if you’re into binaural beats, mindfulness, or brainwave audio apps.

### 4/5 — Good app

*2025-12-04*

I like it a lot, my only complaint is that the app has to be open and your phone has to be unlocked, would be better if it could play like music does even if your phone is locked or you want to use another app. If they fixed that it would be amazing

**Developer response:** Thank you for the suggestion. The upcoming update allows the sound to continue in the background, and will be available shortly. I appreciate the feedback and happy you are enjoying the app!
