The lack of updates since May 2022 suggests a static market position that risks obsolescence as competitors iterate on data visualization and alert accuracy. ## Monetization Strategy - **Model:** Free - **Tiers:** Free access to all features - **Analysis:** The app operates on a free model with no visible subscription or IAP gates, focusing on utility and data distribution. ## 🟢 User Sentiment (Medium Confidence: 17 of 17 reviews analyzed) {#user-sentiment} - **Overall Rating:** 4.89/5 - **Platform Split:** iOS 4.9/5 (18 ratings) - **Overall Sentiment:** Thrilled ### Top Praises - **Customizable notification settings for magnitude and distance allow users to filter out irrelevant earthquake alerts** - **Visual map interface provides immediate and clear data for tracking global tectonic activity and volcanology** - **Timely earthquake notifications provide critical information faster than news outlets or internet search results** ### Top Complaints (Impact Areas) - **Inaccurate location filtering causes users to receive notifications for earthquakes thousands of miles away** ## SWOT Analysis {#swot} **Core Strengths:** - Granular notification thresholds for custom locations - Dedicated watchOS app for real-time monitoring **Growth Levers:** - Android expansion to capture broader user base - Refining USGS data parsing to remove false tsunami tags ## Recent Changes (v2 → v3) {#recent-changes} The app remains in a dormant state with no functional changes, though the analytical outlook has shifted to prioritize the risk of total service failure due to long-term data-feed neglect. **Overall trend**: Declining **Compared at**: 2026-09-05 ### High-impact changes - **[Added] New Threat: Data-feed instability** (swot) ### Medium-impact changes - **[Shifted] Market Position Tone** (positioning) - **[Added] New Threat: Competitive Pressure** (swot) ## What's New - **Latest (v2.8.3, 4 years ago):** Expanded free earthquake notifications to four custom locations and launched a dedicated macOS Earthquake Monitor app. ## App Momentum (Zombie) {#momentum} - Dormant development for 48+ months. - Maintains high user rating despite inactivity. > **Cadence:** 1 total versions · 1 majors in last 6 months · 1564 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Earthquake Monitor is a market-leading weather app that is completely free. With a 4.89/5 rating from 18 reviews, it delivers strong user satisfaction. > **Bottom Line:** The high rating rests on the utility of granular alerts, but the 4-year development gap makes the app vulnerable to any competitor that fixes the location-filtering bugs. Addressing these technical regressions would stabilize the user base while the Android expansion is evaluated. **Best for:** Individuals living in seismically active regions or those requiring real-time monitoring of global earthquake activity. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Audit USGS data parsing logic because minor quakes trigger false tsunami warnings → improve alert accuracy ### Outlook: Declining The seismic monitoring category is shifting toward real-time accuracy and multi-platform accessibility, leaving Earthquake Monitor exposed due to its stagnant release cadence. Without a return to active maintenance, the app will likely lose its high-rating status as technical regressions accumulate and user expectations for alert precision rise. - 🔴 The 48-month development freeze creates a technical debt risk that will eventually break the USGS data feed, leading to total service failure. - 🔴 Persistent user complaints regarding inaccurate location filtering erode trust in the notification system, which is the app's primary value proposition. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.89/5 | | Total Reviews | 18 | | Sentiment | Thrilled (85/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Earthquake Monitor** (this app) | 4.89/5 | Thrilled | David Gross | | [Bauernkalender](https://marlvel.ai/apps/ch-swift-bauernkalender) | N/A/5 | N/A | Swift Management AG | | [Forecast & What to Wear](https://marlvel.ai/apps/com-appsforparents-weatherforkids) | 4.2/5 | N/A | Natalia Jakubczyk-Gajewska | | [Weather&Clothes](https://marlvel.ai/apps/com-air-weather_and_clothes) | 2.7/5 | N/A | fk.system | | [처음날씨 - 잠금화면 및 알람으로 오늘의 날씨를!](https://marlvel.ai/apps/com-woozuda-weather) | 4.2/5 | N/A | WOOZUDA | | [미세미세 - 미세먼지, 초미세먼지, 날씨](https://marlvel.ai/apps/cheehoon-ha-particulateforecaster-particulateforecaster) | 4.8/5 | Excited | LifeOverflow Inc. | ## Company Profile - **Developer:** David Gross - **Website:** [https://davidgrossapps.com](https://davidgrossapps.com) - **Social:** [YouTube](https://www.youtube.com/davidgrossapps) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/earthquake-monitor/id976359729?uo=4) - **Dev Site:** [Official Website](https://davidgrossapps.com) - **Sources:** Developer website content, App store metadata, User reviews. ## Related Intel Reports - [*Bauernkalender*](https://marlvel.ai/apps/ch-swift-bauernkalender) (Swift Management AG) · N/A Rating - [*Forecast & What to Wear*](https://marlvel.ai/apps/com-appsforparents-weatherforkids) (Natalia Jakubczyk-Gajewska) · 4.2/5 Rating - [*Weather&Clothes*](https://marlvel.ai/apps/com-air-weather_and_clothes) (fk.system) · 2.7/5 Rating - [*처음날씨 - 잠금화면 및 알람으로 오늘의 날씨를!*](https://marlvel.ai/apps/com-woozuda-weather) (WOOZUDA) · 4.2/5 Rating - [*미세미세 - 미세먼지, 초미세먼지, 날씨*](https://marlvel.ai/apps/cheehoon-ha-particulateforecaster-particulateforecaster) (LifeOverflow Inc.) · 4.8/5 Rating | Positive Sentiment - [*너의날씨: 미세먼지, 지도, 레이더, 캐릭터, 위젯*](https://marlvel.ai/apps/kr-guzi-yourweather) (구지랩(GuziLab)) · 5.0/5 Rating - [*ชายฝั่ง รู้ทันระดับน้ำ*](https://marlvel.ai/apps/hii-pttep-chaifang-mobile) (Hydro Informatics Institute) · 4.9/5 Rating - [*ภัยพิบัติไทย*](https://marlvel.ai/apps/biz-harmoniz-earthquake_alert_thai) (Harmoniz InterSoftware) · N/A Rating - [*13abc First Alert Weather*](https://marlvel.ai/apps/com-gray-wtvg-13abc-weather) (Gray Television Group, Inc.) · 4.6/5 Rating - [*13WarnMe*](https://marlvel.ai/apps/13warnme) (Local TV LLC) · 3.0/5 Rating ## Frequently Asked Questions {#faq} ### Is Earthquake Monitor free to use?
