## Review summary

Delta Waves+ is praised as an effective, simple sleep aid with focused brainwave audio. However, users repeatedly report price increases, ads, and monetization that degrades value. Playback reliability is a major issue—ads can interrupt sound, and background/screen-off playback often fails, with some iPad users needing headphones. Updates that remove beloved content further frustrate users. The free tier is very limited. Overall, it can work well for some, but cost, reliability, and feature changes significantly dampen satisfaction for many.

### Pros

- Effective sleep aid for many users when it works
- Simple, focused brainwave app with minimal distractions
- One-time purchase option perceived as good value by some
- Positive feedback on delta waves and rain ambience as sleep aids

### Cons

- Price increases and paid upgrades/subscriptions reducing perceived value
- Ads in the free version disrupt playback and can cause audio to stop
- Audio playback reliability issues, including lack of background playback and device-specific problems (e.g., iPad requiring headphones)
- Updates/feature removals have reduced beloved content, diluting the experience
- Free tier is very limited (short listening time and few songs)
