The lack of recent activity signals a low-priority maintenance posture relative to active health-utility competitors. ## Monetization Strategy - **Model:** Free - **Tiers:** Free with ads - **Analysis:** The app is entirely free and monetized through ad-supported inventory. ## 🟢 User Sentiment (Medium Confidence: 11 of 11 reviews analyzed) {#user-sentiment} - **Overall Sentiment:** Excited ### Top Praises - **The blood type calculation tool provides a quick and helpful reference for users needing fast results** ### Top Complaints (Impact Areas) - **Users report the app provides inaccurate blood type results that do not match clinical laboratory testing** ## SWOT Analysis {#swot} **Core Strengths:** - Simple ABO gene trait logic provides fast reference **Growth Levers:** - Integration of verified clinical disclaimers to manage expectations ## Recent Changes (v2 → v3) {#recent-changes} The intelligence report identifies a shift in strategic outlook, moving from a recommendation to add disclaimers to a formal proposal to sunset the product due to persistent clinical inaccuracy and brand risk. **Overall trend**: Declining **Compared at**: 2026-08-06 ### High-impact changes - **[Shifted] Strategic Pivot to Sunset** (positioning) ### Medium-impact changes - **[Shifted] Threat Profile Update** (swot) - **[Shifted] Market Outlook Refinement** (positioning) ## What's New - **Latest (v3.1, 4 years ago):** General bug fixes and performance improvements. ## App Momentum (Zombie) {#momentum} - No updates since August 2021 - Maintenance-mode status for four years > **Cadence:** 1 total versions · 0 majors in last 6 months · 1811 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Pocket Blood Type Calculator is a market-leading health & fitness app that is completely free. > **Bottom Line:** Pocket Blood Type Calculator serves as a basic reference tool, but its failure to match clinical diagnostics and four-year maintenance gap erode user trust, so the developer should either implement rigorous clinical disclaimers or sunset the product to avoid further brand damage. **Best for:** Individuals interested in genetic blood type probability and blood-type-based dietary planning. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] Audit calculation logic because users report inconsistent results for specific parental combinations → improve result reliability ### Outlook: Declining The health-utility market is consolidating around apps that offer verified clinical integration or hardware-linked diagnostics. Pocket Blood Type Calculator remains in maintenance mode, which leaves it exposed to churn as users migrate to more accurate, frequently updated alternatives. - 🔴 The four-year update gap leaves the app vulnerable to modern competitors, which erodes the user base as expectations for diagnostic accuracy rise. - 🔴 User reports of inaccurate results compared to clinic tests create a trust deficit that prevents the app from scaling as a reliable health utility. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Sentiment | Excited (65/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Pocket Blood Type Calculator** (this app) | N/A/5 | Excited | Putu Angga Risky Raharja | | [GoTall - Height Predictor](https://marlvel.ai/apps/gotall-height-predictor) | 4.6/5 | n/a | Grow Labs LLC | | [Mind - Méditations guidées](https://marlvel.ai/apps/mind-m-ditations-guid-es) | 4.6/5 | Excited | MIND AND CIE | | [Strava: Run, Bike, Walk](https://marlvel.ai/apps/strava-run-bike-walk) | 4.7/5 | n/a | Strava, Inc. | | [Taller AI: Height Maximizer](https://marlvel.ai/apps/taller-ai-height-maximizer) | 4.7/5 | Excited | Leadimize | | [TallerTeen - Grow Taller Now](https://marlvel.ai/apps/tallerteen-grow-taller-now) | 4.7/5 | n/a | Viral App Developement LLC | ## Company Profile - **Developer:** Putu Angga Risky Raharja - **Website:** [https://www.imedical-apps.com](https://www.imedical-apps.com) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/pocket-blood-type-calculator/id1506913005?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=com.imedicalapps.pocketbloodtypecalculator&hl=en&gl=us) - **Dev Site:** [Official Website](https://www.imedical-apps.com) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*GoTall - Height Predictor*](https://marlvel.ai/apps/gotall-height-predictor) (Grow Labs LLC) · 4.6/5 Rating - [*Mind - Méditations guidées*](https://marlvel.ai/apps/mind-m-ditations-guid-es) (MIND AND CIE) · 4.6/5 Rating | Positive Sentiment - [*Strava: Run, Bike, Walk*](https://marlvel.ai/apps/strava-run-bike-walk) (Strava, Inc.) · 4.7/5 Rating - [*Taller AI: Height Maximizer*](https://marlvel.ai/apps/taller-ai-height-maximizer) (Leadimize) · 4.7/5 Rating | Positive Sentiment - [*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 - [*Bubblic: Connect with people.*](https://marlvel.ai/apps/bubblic-connect-with-people) (Bubblic Inc.) · 4.6/5 Rating | Excellent Sentiment - [*evolum - Meditation & Yoga*](https://marlvel.ai/apps/evolum-meditation-yoga) (Evolum) · 4.7/5 Rating | Positive Sentiment - [*Holoholo: Daily Memories*](https://marlvel.ai/apps/holoholo-daily-memories) (For Pedestrians LLC.) · 4.4/5 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.
