<!-- speakable-end -->

<!-- section:pm-actions -->
### PM Action Plan (Next Best Moves)

- [ ] [SUNSET] Sunset Ocarina Fingering because it is non-functional and lacks maintenance → remove brand liability
<!-- /section:pm-actions -->

<!-- section:outlook -->
### Outlook: Declining

The music-utility market is consolidating around apps with active maintenance and interactive features. Ocarina Fingering is effectively a zombie asset that provides no value to the user, and sunsetting it is the only logical path forward.

- 🔴 The app has been silent for over 94 months, indicating a complete abandonment of the product.
- 🔴 Critical launch failures prevent any user engagement, ensuring the app remains at the bottom of the category.
