<!-- section:market-position -->
## Market Position {#market-position}

Yuun occupies the Reference category with a specialized focus on traditional Chinese almanac data. The lack of updates since the initial release 12 days ago suggests a maintenance-heavy posture rather than active market expansion.
<!-- /section:market-position -->

## Monetization Strategy
- **Model:** Freemium
- **Tiers:** Free public almanac, Pro tier for detailed Good/Avoid analysis
- **Analysis:** The freemium model gates detailed analysis behind a Pro tier while maintaining a free daily utility for broad reach.

<!-- section:swot -->
## SWOT Analysis {#swot}

**Core Strengths:**
- Birth profile personalization creates data-driven switching costs

**Growth Levers:**
- Targeting users who reject Western astrology and horoscopes


<!-- /section:swot -->
## Recent Changes (v2 → v3) {#recent-changes}

Yuun has pivoted its market positioning to emphasize the exclusion of Western astrology as a deliberate retention strategy for traditionalists. This shift clarifies the app's niche within the Reference category while maintaining the same maintenance-mode development status observed since launch.

**Overall trend**: Stable
**Compared at**: 2026-09-05

### High-impact changes
- **[Shifted] Explicit Anti-Astrology Positioning** (positioning)

### Medium-impact changes
- **[Shifted] SWOT Analysis Refinement** (swot)

<!-- section:momentum -->
## App Momentum (Maintenance) {#momentum}

- Launched initial version 12 days ago.
- No updates since initial release.

> **Cadence:** 1 total versions · 0 majors in last 6 months · 12 days since last update

<!-- /section:momentum -->

<!-- section:so-what -->
## The "So What?" (Strategic Takeaway) {#so-what}

Yuun: Chinese Almanac is a reference app that is free with in-app purchases.

<!-- speakable-start -->
> **Bottom Line:** Yuun secures a niche by stripping away Western astrology, but the lack of updates since the initial release threatens to stall user acquisition. Establishing a consistent content cadence would validate the Pro tier's value to users seeking reliable cultural reference tools.
<!-- speakable-end -->

**Best for:** Individuals interested in traditional Chinese lunisolar dates, cultural customs, and personalized daily activity planning.

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

- [ ] [MAINTAIN] Audit the release cadence because the app has been in maintenance mode since launch → establish a reliable update schedule.
<!-- /section:pm-actions -->

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

The Chinese almanac market remains stable, with demand driven by cultural adherence rather than rapid feature innovation. Yuun's ability to retain users depends on maintaining content accuracy, which requires a more active update cadence than the current maintenance-only posture.

- ⚪ The app has remained in maintenance mode since its release 12 days ago, suggesting a stable but inactive development cycle.
