<!-- /section:features -->

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

The app lacks a footprint in the US store rankings, and the zero rating count across both iOS and Android platforms signals a lack of active user engagement.
<!-- /section:market-position -->

## Monetization Strategy
- **Model:** Free
- **Tiers:** Free access to all testing and simulation tools
- **Analysis:** The app operates on a fully free, ad-supported model with no current IAP or subscription gates.

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

**Core Strengths:**
- Offline-first architecture enables testing in low-connectivity environments

**Critical Frictions:**
- Zero rating count across both platforms

**Growth Levers:**
- Integrating formal medical disclaimers to increase trust

**Market Threats:**
- Competitors with professional screening modes drain high-intent users

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

The app has transitioned from an active, feedback-driven diagnostic tool to an unrated, low-visibility product facing new direct competition.

**Overall trend**: Declining
**Compared at**: 2026-05-14

### High-impact changes
- **[Declined] Loss of User Sentiment Data** (sentiment) — User sentiment data is now null, and the rating count has dropped to zero from 32.
- **[Shifted] Competitive Landscape Realignment** (positioning) — The app is no longer benchmarked against Color Blind Pal, but is now compared to Color Blindness Test Ishihara, which offers professional screening and status reports.

### Medium-impact changes
- **[Shifted] SWOT Analysis Redefinition** (swot) — Weaknesses shifted from timer logic and lack of feedback to a zero rating count; strengths shifted from clinical simplicity to offline-first architecture.
- **[Shifted] PM Action Item Pivot** (positioning) — Action items shifted from fixing timer logic to implementing rating prompts to address the zero-rating trust barrier.

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

- **Latest (v4.2.0, 1 weeks ago):** Optimized Color Blind Test performance and Ishihara plate loading with UI/UX refinements.
<!-- /section:whats-new -->

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

- Ships minor performance improvements.
- Maintains consistent update cadence.

> **Cadence:** 2 total versions · 0 majors in last 6 months · 11 days since last update · 5 days avg between updates

<!-- /section:momentum -->

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

Color Blind Test - Ishihara is an established health & fitness app that is completely free.

<!-- speakable-start -->
> **Bottom Line:** The app provides a functional screening tool but lacks the social proof and professional depth to compete with established rivals, so the PM should prioritize rating acquisition to build the trust necessary for user retention.
<!-- speakable-end -->

**Best for:** Individuals concerned about color vision deficiency, parents screening children, and designers needing accessibility verification tools.

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

- [ ] [INVEST] [HIGH IMPACT] Implement a prompt for user ratings after the first successful test completion because current rating count is zero → increase social proof. — *The zero rating count prevents organic discovery and trust, which are critical for health-related apps.* _(trade-off: deprioritize Pause the development of new simulation filters — rating acquisition is a higher priority for long-term survival.)_
<!-- /section:pm-actions -->

<!-- section:feature-gaps -->
### Feature Gaps vs Competitors

- Professional screening mode (available in Color Blindness Test Ishihara but missing here)
- Personalized vision status reports (available in Color Blindness Test Ishihara but missing here)
<!-- /section:feature-gaps -->

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

The category for mobile vision screening is consolidating around apps that offer professional-grade reporting and clinical validation. Without a shift toward professional certification or social proof, this app will remain a low-visibility tool, so the PM must focus on building trust to avoid total stagnation.

- ⚪ Recent updates focused on stability and minor bug fixes, indicating the app remains in a maintenance-heavy development cycle.
- 🔴 The total absence of user ratings across both platforms creates a trust barrier that prevents conversion of new organic traffic.
