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

- [ ] [INVEST] Restore the companion remote recorder app because its removal renders Apollo Sound Injector non-functional → restore core utility
<!-- /section:pm-actions -->

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

The market for mobile-to-desktop audio routing is consolidating around active, supported tools, leaving Apollo Sound Injector exposed as a legacy utility. Without a restoration of the companion component, the app will continue to lose its remaining user base to modern, maintained alternatives.

- 🔴 The removal of the companion recorder app renders the software non-functional, which drives the current negative sentiment trend.
- 🔴 The 11-year update gap signals that development has ceased, leaving the app unable to adapt to modern iOS audio standards.
