## Review summary

Reviews consistently praise Music Speed Changer for its reliable, simple UI and strong tempo/pitch controls, and note its versatility across activities (running, practice, recitations). However, there are recurring concerns about intrusive ads and the lack of an export/markers feature. Overall, users value the app for its core functionality and ease of use but want better ad handling and data/export capabilities.

### Pros

- Reliable and easy-to-use UI
- Powerful tempo/pitch controls (speed changes without changing pitch)
- Versatile across contexts (useful for running, practice, Quran recitations, etc.)
- Long-standing user satisfaction and trust (used for years)

### Cons

- Intrusive/malicious ads and deceptive ad behavior (fake close button, data usage)
- Missing export/markers feature (cannot export markers from tracks; users want this capability)
