## Review summary

Users praise BrainWave for its broad library of tones and multi‑purpose use (sleep, focus, anxiety, meditation) and its one‑time purchase model with background playback. However, a common chorus across reviews notes an aging UI, reliability bugs, and a desire for more frequent content updates and customization options, including smoother handling of interruptions and external casts.

### Pros

- Large variety of programs, frequencies, and ambiance options plus the ability to blend in your own background audio.
- Useful for many goals—sleep, focus, anxiety relief, meditation—and works well as background listening while using other apps.
- One-time purchase with no ongoing subscription or paywalls, offering good long‑term value.
- High-quality content and nature sounds that many users find beneficial for creativity and mood.

### Cons

- Outdated UI and usability issues; interface feels old and saving favorites is confusing, signaling a major update is due.
- Bugs and reliability problems (e.g., apps launching unexpectedly, background interference) reported by multiple users.
- Content repertoire updates are infrequent; users want new tones/frequencies and refreshed options.
- Limited customization and interruption handling (locked settings; desire for restart after interruptions and better cross-device casting).
