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

- [ ] [PIVOT] Audit Android performance because the 0.3 rating gap vs iOS indicates technical friction → improve Android retention
<!-- /section:pm-actions -->

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

The sleep-aid market is consolidating around apps with high-frequency feature updates and social integration. Sleep Sounds - SleepMaster remains stable due to its content library, but the lack of technical investment on Android threatens its long-term viability.

- ⚪ The release cadence is currently limited to content updates, which maintains existing users but fails to attract new segments.
- 🔴 The Android-iOS rating gap indicates technical debt, which will likely increase churn if left unaddressed in the next quarter.
