<!-- /section:market-position -->

## Monetization Strategy
- **Model:** Freemium
- **Tiers:** Free tier with limited access, Paid subscription for unlimited access
- **Price:** iOS: $1.99

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

**Core Strengths:**
- Interactive assembly diagrams replace manual index lookups
- Offline-first architecture ensures utility in signal-blocked workshop environments

**Growth Levers:**

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

Strategic focus shifted from lowering the acquisition barrier via a free search utility to prioritizing catalog library depth as the primary lever for professional retention. Positioning now frames the $1.99 entry price as a professional filter rather than a competitive liability.

**Overall trend**: Stable
**Compared at**: 2026-08-15

## The "So What?" (Strategic Takeaway) {#so-what}

Auto Parts Catalog is a reference app that is free with in-app purchases.

<!-- speakable-start -->
> **Bottom Line:** Expanding the vehicle library would address the primary barrier to professional adoption, unlocking higher subscription conversion among mechanics who currently rely on manufacturer-specific portals.
<!-- speakable-end -->

**Best for:** Car owners, professional mechanics, and parts sellers who require quick, visual access to vehicle assembly diagrams.

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

- [ ] [INVEST] Expand vehicle library to include high-volume segments because current catalog breadth is the primary barrier to professional adoption → increase daily active usage
<!-- /section:pm-actions -->

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

The reference utility market is consolidating around manufacturer-provided mobile tools, which creates a high barrier for independent catalogs. Auto Parts Catalog must prioritize library depth to maintain its value proposition against free, official alternatives.

- ⚪ The latest release added BMW support, confirming that the developer is prioritizing library expansion over new feature development.
