<!-- speakable-start -->
> **Bottom Line:** Chords: intervals and scales offers a unique hardware-based feedback loop, but the lack of development cadence threatens its long-term viability. Monetizing the ad-free experience would unlock revenue from the existing user base while the core scoring logic requires adjustment to prevent churn.
<!-- speakable-end -->

**Best for:** Music students and hobbyists learning piano, guitar, or ukulele who want to master music theory and ear training.

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

- [ ] [INVEST] Ship a paid ad-free tier because users explicitly request it in reviews → increase revenue
<!-- /section:pm-actions -->

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

The music education category is shifting toward gamified, mobile-first experiences that prioritize user retention through frequent content updates. Chords: intervals and scales remains static, and its failure to address basic user requests regarding scoring and ad-removal will likely accelerate its decline in the coming quarters.

- 🔴 The 962-day update gap indicates the app is in maintenance mode, which will lead to gradual user attrition as competitors release modern features.
- 🔴 Strict scoring logic and lack of difficulty scaling frustrate users, which compounds the churn risk already present due to the lack of new content.
