The outtake for Color Blind Test - Ishihara
Strengths to defend, gaps to attack
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
What are the next best moves?
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: Pause the development of new simulation filters — rating acquisition is a higher priority for long-term survival.
A counter-intuitive read
The lack of monetization is a strategic liability, as it prevents the app from funding the clinical validation required to move beyond a casual, low-trust tool.
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)
Key Takeaways
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.
Where Is It Heading?
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.
