US Market. No publisher influence. > **Key Insight:** Hazards and Population Mapper is a reference app by NASA. ## Metadata & Market Performance - **Publisher:** NASA - **Category:** Reference - **Target Audience:** Disaster risk managers, humanitarian response organizations, public health professionals, and journalists requiring rapid assessment of hazardous events. - **Platforms:** iOS - **Version Audited:** 2.0 - **Audit Date:** 2026-04-03 - **Signal Count:** 0 reviews analyzed - **Confidence:** Low (0.1/1.0) - **App Store ID (iOS):** 1092168898 - **Bundle ID:** gov.nasa.gsfc.HazPop - **Data Window:** Analysis based on signals collected up to 2026-04-03 ## Executive Snapshot Hazards and Population Mapper (HazPop) is a specialized geospatial utility developed by NASA and Columbia University. It enables disaster managers and journalists to visualize real-time natural hazards (fires, earthquakes, pollution) in direct relation to population density and critical infrastructure like nuclear power plants. Its primary value lies in providing rapid situational awareness for humanitarian and public health emergencies, though it is not intended for high-resolution, localized response. ## App DNA (Features & Intent) - **[Standard] Natural Hazard Mapping:** Visualizes active fires, earthquake alerts, and air pollution data in near real-time. * *User Intent:* Users want timely prompts to stay engaged without missing updates. - **[Differentiator] Population Estimation Service:** Calculates total population and land area within a user-defined circular radius on the map. - **[Differentiator] Infrastructure Overlay:** Displays locations of major dams and nuclear power plants with facility-specific details. * *User Intent:* Users expect intelligent, adaptive experiences that learn from their behavior. - **[Standard] Proximity Sorting:** Sorts hazardous events and infrastructure by distance from the user's current location. * *User Intent:* Users seek enhanced value through premium features. - **[Basic] Distance Measurement:** Calculates distance between the user's location and map points or between two arbitrary points. ## Monetization Strategy - **Model:** Free - **Tiers:** Completely free to use with no mentioned in-app purchases or subscription tiers. - **Analysis:** The app serves as a public service tool provided by NASA and Columbia University, prioritizing data accessibility over monetization. ## SWOT Analysis **Core Strengths:** - Institutional credibility of NASA and Columbia University - Unique Population Estimation Service (PES) utility - Integration of real-time hazard data with socioeconomic layers - Completely free and open access to scientific data **Critical Frictions:** - Product is stale (last updated 2019) - Limited to iOS platform only - Coarse data resolution limits use for specific local response - Low user engagement and rating volume **Growth Levers:** - Modernize UI/UX to capture users frustrated by legacy interface - Develop an Android version for global humanitarian use - Integrate real-time push notifications for hazard alerts - Incorporate higher-resolution imagery and demographic data **Market Threats:** - Technical obsolescence due to lack of OS compatibility updates - Commercial GIS platforms integrating similar socioeconomic overlays - Specialized hazard apps (e.g., fire/quake trackers) offering better real-time features ## The "So What?" (Strategic Takeaway) Hazards and Population Mapper is an established reference app that is completely free. With a 3.33/5 rating from 6 reviews, it shows polarized user reception. **Strategic Opportunity:** While Hazards and Population Mapper benefits from institutional credibility of nasa and columbia university, its vulnerability lies in product is stale (last updated 2019). A challenger could exploit this by focusing on modernize ui/ux to capture users frustrated by legacy interface. **Best for:** Disaster risk managers, humanitarian response organizations, public health professionals, and journalists requiring rapid assessment of hazardous events. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 3.33/5 | | Total Reviews | 6 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 5 analyzed | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Hazards and Population Mapper** (this app) | 3.33/5 | N/A | NASA | | [Hallow: Prayer & Meditation](https://marlvel.ai/intel-report/reference/hallow-prayer-meditation) | 4.9/5 | Frustrated | Hallow, Inc. | | [Pillars: Prayer Times & Qibla](https://marlvel.ai/intel-report/reference/com-muslimplus-muslimplus) | 4.8/5 | Mixed | The Pillars Group Ltd | | [Aim High Air Force](https://marlvel.ai/intel-report/reference/com-airforce-aimhighapp) | N/A/5 | N/A | HQ US Air Force Recruiting Service | | [The CIA World Factbook](https://marlvel.ai/intel-report/reference/name-xianan-chen-theworld) | N/A/5 | Mixed | 贤安 陈 | | [اسبوع الالام](https://marlvel.ai/intel-report/reference/somiex-holyweek-arabic) | N/A/5 | Thrilled | Sameh Halim | ## Company Profile - **Developer:** NASA ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/hazards-and-population-mapper/id1092168898?uo=4) - **Sources:** App store metadata. ## Related Intel Reports - [*Hallow: Prayer & Meditation*](https://marlvel.ai/intel-report/reference/hallow-prayer-meditation) (Hallow, Inc.) — 4.9/5 Rating | Negative Sentiment - [*Pillars: Prayer Times & Qibla*](https://marlvel.ai/intel-report/reference/com-muslimplus-muslimplus) (The Pillars Group Ltd) — 4.8/5 Rating | Mixed Sentiment - [*Aim High Air Force*](https://marlvel.ai/intel-report/reference/com-airforce-aimhighapp) (HQ US Air Force Recruiting Service) — N/A Rating | N/A Sentiment - [*The CIA World Factbook*](https://marlvel.ai/intel-report/reference/name-xianan-chen-theworld) (贤安 陈) — N/A Rating | Mixed Sentiment - [*اسبوع الالام*](https://marlvel.ai/intel-report/reference/somiex-holyweek-arabic) (Sameh Halim) — N/A Rating | Excellent Sentiment - [*Translate Ease*](https://marlvel.ai/intel-report/reference/com-spellspeed-spellspeed-everlytranslate) (GOOD STUDY NETWORK TECHNOLOGY LIMITED) — N/A Rating | N/A Sentiment - [*World Factbook Pro Edition*](https://marlvel.ai/intel-report/reference/com-appventions-worldfacts2010pro) (Appventions) — N/A Rating | N/A Sentiment - [*Pocket Rally Dog Obedience*](https://marlvel.ai/intel-report/reference/com-blueribbondogs-pocketrally2016) (Blue Ribbon Dogs) — 4.8/5 Rating | Excellent Sentiment - [*Half-Staff Flag Alerts*](https://marlvel.ai/intel-report/reference/com-apps4world-halfstaff) (Apps4World) — N/A Rating | N/A Sentiment - [*Turf MD*](https://marlvel.ai/intel-report/reference/org-apsnet-apsreference-turfmd) (American Phytopathological Society) — N/A Rating | N/A Sentiment ## Methodology This report was generated by Marlvel.ai's 3-stage AI intelligence pipeline: 1. **Feature & Positioning Extraction** — Analyzes app metadata, developer website content, and version history to identify key features, target audience, and competitive positioning. 2. **Sentiment Analysis** — Processes user reviews (minimum 5 reviews required) to extract praise themes, complaint themes, and overall sentiment with evidence quotes. 3. **Intelligence Synthesis** — Combines stages 1 & 2 with App Store rankings to produce SWOT analysis, executive summary, and actionable insights. - **Confidence Score:** 0.1/1.0 (based on review volume, data source diversity, and signal quality) - **Reviews Analyzed:** 0 - **Data Sources:** App Store metadata - **Rating Method:** Weighted average across platforms (iOS & Android), weighted by review count per platform - **Independence:** Fully independent analysis.
