<!-- speakable-start -->

<!-- speakable-end -->

**Best for:** Students, contractors, or hobbyists requiring basic geometric area calculations and unit conversions.

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

- [ ] [SUNSET] Sunset the application because it has been in maintenance mode for 10 years → reduce brand liability
<!-- /section:pm-actions -->

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

The utility market is consolidating around apps with frequent update cadences and modern UI standards. Area Calculator Free is exposed due to its lack of maintenance, so the PM should plan for a graceful exit.

- 🔴 The 10-year update gap indicates the app is in terminal decline, which increases the risk of store removal for abandonment.
