Percentage Calculator %: Tax is an utilities app that is free with in-app purchases.

<!-- speakable-start -->
> **Bottom Line:** Percentage Calculator %: Tax relies on its ad-free promise to retain users, but the 11-month update silence risks technical obsolescence. The PM should pivot to a feature-led growth strategy to justify the subscription tier, as the current utility set is too static to drive long-term conversion.
<!-- speakable-end -->

**Best for:** Individuals and professionals needing quick, ad-free percentage-based tax calculations for GST, VAT, or general sales tax.

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

- [ ] [INVEST] Ship a feature update to the tax-saving logic because the current 11-month silence risks churn → increase subscription conversion
<!-- /section:pm-actions -->

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

The tax-utility market is consolidating around apps with frequent live-ops and feature updates. Percentage Calculator %: Tax remains exposed due to its 11-month update gap, which signals to users that the product is no longer a priority for the developer.

- 🔴 The 11-month update silence suggests the product is in maintenance mode, which prevents the feature expansion needed to compete with active rivals.
- 🔴 Lack of recent feature investment limits the ability to justify the subscription tier, which will likely lead to declining conversion rates over time.
