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

**Core Strengths:**
- Seasonal feature integration (Ehomaki finder) creates a recurring discovery loop.
- Offline-first design removes connectivity dependency.

**Growth Levers:**
- Localized sensor-reset guides could reduce orientation-related support volume.


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

Regional accessibility documentation now explicitly identifies China as the primary failure point, while the app's maintenance status remains unchanged after 236 days of inactivity.

**Overall trend**: Stable
**Compared at**: 2026-09-02

### Medium-impact changes
- **[Shifted] Regional Lock-out Specification** (swot)

### Low-impact changes
- **[Improved] Feature Positioning** (features)

<!-- section:whats-new -->
## What's New

- **Latest (v00.00.19, 7 months ago):** Introduced five new design styles and a compass calibration tool to detect and resolve inaccuracies.
<!-- /section:whats-new -->

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

- Shipped calibration tool in latest release.
- Dormant for 7 months.

> **Cadence:** 1 total versions · 1 majors in last 6 months · 236 days since last update

<!-- /section:momentum -->

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

Compass_S is a navigation app that is free with in-app purchases.
It holds a 4.62/5 rating from 282 reviews.

<!-- speakable-start -->
> **Bottom Line:** Compass_S provides a specialized seasonal utility, but the regional access failures and hardware-dependent orientation issues currently undermine its reliability. Addressing these functional gaps would unlock broader utility for the existing user base.
<!-- speakable-end -->

**Best for:** Casual users in Japan seeking simple navigation and participants in seasonal traditions like Setsubun.

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

- [ ] [PIVOT] Audit regional access logic because users report the app is unresponsive outside of China → restore global utility
<!-- /section:pm-actions -->

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

The navigation utility market is consolidating around tools that offer broader, global sensor support and frequent updates. Compass_S remains exposed due to its regional lock-outs and lack of recent feature investment, which will likely lead to further rating erosion as hardware standards evolve.

- 🔴 The 7-month development silence suggests a maintenance-only posture, which leaves the app vulnerable to OS-level changes that could break sensor integration.
- 🔴 Regional functionality restrictions (unresponsive outside China) prevent the app from scaling beyond its current, limited user segment.
