## Review summary

Users generally find Pitch Perfector effective for improving pitch recognition, especially for beginners and children, appreciating its variety of instrument sounds and structured progression. However, multiple reviews mention usability issues like the lack of an exit button, loud ads disrupting listening, occasional sound glitches, and the app forcing multiple instruments simultaneously. Beginners sometimes find the difficulty level challenging without gentler guidance. Overall, the app is well-regarded for ear training but has some usability improvements to consider.

### Pros

- Effective for beginners and children to improve pitch recognition and ear training.
- Offers various instrument sounds making learning engaging and fun.
- Well organized and structured progressive difficulty levels.
- Affordable with optional instrument packs and no ads in premium version.
- Helps improve relative pitch and is suitable for users with little musical knowledge.

### Cons

- No built-in exit or back button functionality; app has to be manually closed via home button and memory management.
- Advertisements are very loud compared to app sounds, which can be disruptive during attentive listening.
- Some users experience sound glitches or distortion especially after returning from other apps or ads.
- Lack of options to focus on a single instrument; multiple instruments play simultaneously by default causing confusion.
- Some users find the app's difficulty too advanced for beginners due to intervals and note choices, requiring gentler introduction.
