The core product remains unchanged, but the competitive assessment now emphasizes its status as a legacy tool rather than a viable sensor utility. **Overall trend**: Declining **Compared at**: 2026-08-22 ### High-impact changes - **[Declined] Outlook Trend Downgrade** (positioning) ### Medium-impact changes - **[Shifted] Legacy Positioning** (positioning) - **[Added] OS Compatibility Threat** (swot) ## What's New - **Latest (v1.0, 10 years ago):** General functional improvements with no new features. ## App Momentum (Zombie) {#momentum} - No updates since 2015. - Maintenance-mode status confirmed. > **Cadence:** 1 total versions · 0 majors in last 6 months · 3953 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} EMF Radiation Detector is an utilities app that is completely free. With a 3.44/5 rating from 200 reviews, it shows mixed user reception. > **Bottom Line:** EMF Radiation Detector provides basic magnetic field readings, but the lack of instructional documentation leaves users unable to interpret safety risks. Adding a reference scale for common household items would address the primary frustration driving negative sentiment. **Best for:** Individuals concerned about electromagnetic radiation exposure from household appliances and electronic devices. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship instructional documentation because users report confusion over safety interpretation -> improve user trust ### Outlook: Declining The utility category is shifting toward more transparent, data-backed health monitoring tools. EMF Radiation Detector remains stagnant, which will likely lead to further rating erosion as users seek more accurate and documented alternatives. - 🔴 The ten-year update gap indicates the app is in maintenance mode, which prevents it from adapting to modern sensor-calibration standards. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 3.44/5 | | Total Reviews | 200 | | Sentiment | Mixed (45/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS | | Key Features | 2 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **EMF Radiation Detector** (this app) | 3.44/5 | Mixed | Ngoc Que Nguyen | | [Sota Connect: Secure Network](https://marlvel.ai/apps/fi-catconnect-sota) | 4.9/5 | N/A | Cat Connect | | [avoVPN Desktop](https://marlvel.ai/apps/avovpn-desktop) | N/A/5 | N/A | Avocado VPN Technologies | | [Free VPN by Free VPN .org™](https://marlvel.ai/apps/free-vpn-by-free-vpn-org) | 4.5/5 | Mixed | Free VPN LLC | | [Fusvob VPN : Super VPN 2026](https://marlvel.ai/apps/com-toplinkc-foxexcellent) | 4.5/5 | Mixed | Fuxin Technology | | [Potatso](https://marlvel.ai/apps/potatso) | 4.4/5 | n/a | Potatso Lab LTD | ## Company Profile - **Developer:** Ngoc Que Nguyen ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/emf-radiation-detector/id1046907307?uo=4) - **Sources:** App store metadata, User reviews. ## Related Intel Reports - [*Sota Connect: Secure Network*](https://marlvel.ai/apps/fi-catconnect-sota) (Cat Connect) · 4.9/5 Rating - [*avoVPN Desktop*](https://marlvel.ai/apps/avovpn-desktop) (Avocado VPN Technologies) · N/A Rating - [*Free VPN by Free VPN .org™*](https://marlvel.ai/apps/free-vpn-by-free-vpn-org) (Free VPN LLC) · 4.5/5 Rating - [*Fusvob VPN : Super VPN 2026*](https://marlvel.ai/apps/com-toplinkc-foxexcellent) (Fuxin Technology) · 4.5/5 Rating - [*Potatso*](https://marlvel.ai/apps/potatso) (Potatso Lab LTD) · 4.4/5 Rating - [*Quantumult X*](https://marlvel.ai/apps/quantumult-x) (Cross Utility Ltd) · 3.8/5 Rating - [*V2Box - V2ray Client*](https://marlvel.ai/apps/v2box-v2ray-client) (techlaim) · 4.6/5 Rating - [*카톡 분석 - 오픈채팅, 카톡 채팅 분석, 통계, 검색*](https://marlvel.ai/apps/com-liger-katalkanalysispaid) (Park Sung Cheol) · N/A Rating - [*로또 황금번호 생성기*](https://marlvel.ai/apps/lotto-lottogold) (jaehwan lee) · N/A Rating - [*도사폰 (만세력 역학도구)*](https://marlvel.ai/apps/app--656) (Softchaser Company Limited) · 5.0/5 Rating ## Frequently Asked Questions {#faq} ### Is EMF Radiation Detector accurate for detecting radiation?
