Key takeaways for Zen Tuner

- The app freezes on launch following the latest update, which erodes the daily active habit and compounds the rating drag.
The SWOT
- Minimalist, ad-free interface provides a high-focus practice environment.
- Integration with DAW plugin standards to capture professional studio workflows.
