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

- [ ] [INVEST] Rebuild background task handling because alarms fail when the app is minimized → increase reliability
<!-- /section:pm-actions -->

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

The alarm utility market is consolidating around native system features, leaving third-party apps like Sleep Music Alarm exposed to reliability gaps. Unless the background execution issues are resolved, the app will struggle to retain users who prioritize consistent wake-up performance over media customization.

- 🔴 Persistent background alarm failures erode user trust, which compounds the negative sentiment regarding intrusive ad placement.
- ⚪ The latest release focuses on stability, indicating a maintenance-only cadence rather than active feature expansion.
