<!-- /section:pm-actions -->

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

The music discovery utility market is consolidating around native platform features, leaving standalone apps like Chart Music in a defensive position. A stability-focused update is necessary to retain the professional user base while the developer assesses the viability of a premium, ad-free model.

- ⚪ The 10-month development silence suggests a maintenance-mode posture, which limits the ability to respond to evolving music store API requirements.
- 🟢 Professional DJs continue to report high satisfaction with the mobile preview functionality, which remains a primary driver for retention.
