Its lack of monetization gates creates a low-barrier entry but limits the revenue needed to compete with professional-grade clinical tools. ## 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. ## SWOT Analysis {#swot} **Core Strengths:** - Simplified Ishihara interface reduces screening friction - Simulator tool provides unique design-accessibility utility **Growth Levers:** - B2B partnerships with design schools for accessibility tools - Premium reporting tiers would unlock revenue streams ## Recent Changes (v3 → v4) {#recent-changes} The app has transitioned from a maintenance-only posture to a proactive development strategy focused on monetization and multi-user utility to counter clinical-grade competitors. **Overall trend**: Mixed **Compared at**: 2026-07-19 ### High-impact changes - **[Shifted] Competitive Landscape Expansion** (positioning) - **[Shifted] Monetization Strategy Pivot** (pricing) ### Medium-impact changes - **[Added] Multi-user Profile Roadmap** (features) - **[Shifted] SWOT Analysis Realignment** (swot) ## Rivals Landscape {#rivals} > Competitive positioning identified by AI analysis of app features, category, and market signals. ### Color Blind Test - Ishihara vs EyeQue Insight - **[EyeQue Insight](https://marlvel.ai/apps/eyeque-insight)** by EyeQue Corporation: EyeQue competes directly by offering vision screening and tracking tools that target the same health-conscious demographic seeking at-home eye diagnostics. - **Key differences:** - Offers comprehensive optical vision screening beyond simple color blindness testing for broader utility - Includes multi-user sharing capabilities that allow families to track vision health on one device - Provides long-term vision tracking data which encourages higher user retention than a static test ### Contenders (Strong Challengers) - **[GoCheck Kids+](https://marlvel.ai/apps/gocheck-kids)** by Gobiquity, Inc.: Users report: goCheck Kids+ targets the professional medical segment, competing for the same clinical screening use case but with a B2B focus. - Integrates directly with Electronic Health Records to streamline clinical workflows for pediatricians - Cloud-based admin portal provides enterprise-level data management that this app lacks ### Peers (What They Do Better) - **[Color Blindness Test Ishihara](https://marlvel.ai/apps/color-blindness-test-ishihara)** by Rina Katrina: This is a direct functional clone that provides the exact same Ishihara testing methodology to the same consumer audience. - Offers a professional screening mode that provides more detailed reporting than this app - Includes personalized vision status reports to help users interpret their specific test results - **[Vision Screening Events App](https://marlvel.ai/apps/vision-screening-events-app)** by OneSight EssilorLuxottica Foundation: This app operates in the medical screening space, focusing on large-scale event management rather than individual consumer testing. - Specialized features for managing high-volume screening events and real-time data capture - Includes specific logistics tracking for sunglass dispensing, a niche not addressed by this app ## What's New - **Latest (v4.2.0, 1 weeks ago):** Optimized Color Blind Test performance and Ishihara plate loading with UI/UX refinements. ## App Momentum (Maintenance) {#momentum} - Ships minor performance improvements. - Maintains fully free, ad-supported model. > **Cadence:** 2 total versions · 0 majors in last 6 months · 11 days since last update · 5 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} Color Blind Test - Ishihara is an established health & fitness app that is completely free. > **Bottom Line:** The app captures the casual screening market through simplicity, but its zero-monetization model prevents it from scaling against clinical-grade rivals, so the PM must prioritize a premium reporting tier to fund long-term development. **Best for:** Individuals concerned about color vision, parents screening children, and designers needing accessibility verification tools. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Introduce premium PDF reporting tier because current free model lacks revenue levers → increase average revenue per user ### Feature Gaps vs Competitors - Multi-user tracking (available in EyeQue Insight but missing here) ### Outlook: Mixed The vision-screening market is consolidating around apps that offer long-term health tracking rather than static tests. Without a transition to a premium model or clinical-grade features, this app will likely remain a low-utility tool for casual users while losing ground to rivals with higher retention loops. - ⚪ Recent updates focused on minor performance improvements, indicating the app remains in a maintenance-mode development cycle. - 🔴 The absence of monetization gates limits the capital available to defend against better-funded competitors entering the vision-screening space. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Mixed | | Outlook | Mixed | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Color Blind Test - Ishihara** (this app) | N/A/5 | N/A | Suman Sharma | | [Color Blindness Test Ishihara](https://marlvel.ai/apps/color-blindness-test-ishihara) | 3.0/5 | N/A | Rina Katrina | | [Vision Screening Events App](https://marlvel.ai/apps/vision-screening-events-app) | N/A/5 | N/A | OneSight EssilorLuxottica Foundation | | [EyeQue Insight](https://marlvel.ai/apps/eyeque-insight) | 3.7/5 | n/a | EyeQue Corporation | | [GoCheck Kids+](https://marlvel.ai/apps/gocheck-kids) | 3.5/5 | N/A | Gobiquity, Inc. | | [GoTall - Height Predictor](https://marlvel.ai/apps/gotall-height-predictor) | 4.6/5 | N/A | Grow Labs LLC | ## Company Profile - **Developer:** Suman Sharma - **Website:** [https://sumansharma1.com.np/](https://sumansharma1.com.np/) - **Social:** [Instagram](https://instagram.com/SumanSharmaTech) · [Facebook](https://facebook.com/SumanSharmaTech) · [X/Twitter](https://twitter.com/SumanSharmaTech) · [LinkedIn](https://linkedin.com/in/SumanSharmaTech) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/color-blind-test-ishihara/id6746558694?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=com.color.blind.test&hl=en&gl=us) - **Dev Site:** [Official Website](https://sumansharma1.com.np/) - **Sources:** Developer website content, About us / company information, App store metadata. ## Related Intel Reports - [*Color Blindness Test Ishihara*](https://marlvel.ai/apps/color-blindness-test-ishihara) (Rina Katrina) · 3.0/5 Rating - [*Vision Screening Events App*](https://marlvel.ai/apps/vision-screening-events-app) (OneSight EssilorLuxottica Foundation) · N/A Rating - [*EyeQue Insight*](https://marlvel.ai/apps/eyeque-insight) (EyeQue Corporation) · 3.7/5 Rating - [*GoCheck Kids+*](https://marlvel.ai/apps/gocheck-kids) (Gobiquity, Inc.) · 3.5/5 Rating - [*GoTall - Height Predictor*](https://marlvel.ai/apps/gotall-height-predictor) (Grow Labs LLC) · 4.6/5 Rating - [*Strava: Run, Bike, Walk*](https://marlvel.ai/apps/strava-run-bike-walk) (Strava, Inc.) · 4.7/5 Rating | Positive Sentiment - [*Taller AI: Height Maximizer*](https://marlvel.ai/apps/taller-ai-height-maximizer) (Leadimize) · 4.7/5 Rating - [*TallerTeen - Grow Taller Now*](https://marlvel.ai/apps/tallerteen-grow-taller-now) (Viral App Developement LLC) · 4.7/5 Rating - [*Activity Tracker・FitnessView*](https://marlvel.ai/apps/activity-tracker-fitnessview) (Funn Media, LLC) · 4.0/5 Rating - [*Avatran Soul*](https://marlvel.ai/apps/avatran-soul) (Avatran GmbH) · N/A Rating ## Methodology {#methodology} This report was generated by Marlvel.ai's 5-stage AI intelligence pipeline: 1. **Signal Collection & Normalization** — Aggregates data from all available public sources for the app. Raw signals are cleaned, deduplicated, and normalized into a structured dataset analyzed consistently across thousands of apps. 2. **Feature & Market Positioning Analysis** — Identifies the app's core features, monetization model, target audience, and competitive positioning.
