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

- [ ] [PIVOT] Ship a feature-update sprint because the 81-day maintenance cadence risks losing professional users to active rivals → increase retention
<!-- /section:pm-actions -->

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

The construction utility market is shifting toward subscription-based models that fund rapid feature iteration, leaving BuildCalc: Material Calculator in a defensive posture. While the one-time purchase model attracts cost-conscious professionals, the lack of recent feature updates threatens to erode the app's competitive edge against more agile rivals.

- 🔴 The 81-day maintenance-only update cadence suggests a lack of active feature investment, which compounds the risk of falling behind subscription-funded competitors.
- 🟢 The privacy-first, no-subscription model creates a defensible position among professional contractors who prioritize data ownership and predictable costs.
