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

- [ ] [MAINTAIN] Ship a minor stability update because the app has been dormant for 156 days → restore user confidence in long-term support
<!-- /section:pm-actions -->

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

The digital hymnal market is currently stable, but Harpa Crista's lack of updates leaves it vulnerable to competitors that offer more frequent feature improvements. The PM should prioritize a stability release to signal continued support for the user base.

- ⚪ The app has remained in a dormant state for over five months, which limits its ability to respond to user feedback.
