The low rating of 2.0 stars across 5 reviews signals that the app fails to meet modern user expectations for accuracy and performance. ## Monetization Strategy - **Model:** Free - **Tiers:** Free - **Analysis:** The app is distributed as a free utility with no visible subscription or IAP gates. ## SWOT Analysis {#swot} **Core Strengths:** - Calibration tool accounts for specific microphone hardware variations **Growth Levers:** - Integration of modern sensor-fusion libraries could improve accuracy ## Recent Changes (v2 → v3) {#recent-changes} The analysis has been updated to include specific technical limitations regarding hardware-based decibel measurement accuracy. **Overall trend**: Declining **Compared at**: 2026-08-13 ### High-impact changes - **[Added] Hardware-limited accuracy weakness** (swot) ### Medium-impact changes - **[Added] Sensor-fusion opportunity** (swot) ## What's New - **Latest (v1.0.2, 8 years ago):** General bug fixes and performance improvements. ## App Momentum (Zombie) {#momentum} - No updates for 8 years. - Maintenance-mode status confirmed. > **Cadence:** 1 total versions · 0 majors in last 6 months · 3051 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Sound Meter - Noise Detector is an utilities app that is completely free. It holds a 2/5 rating from 5 reviews. > **Bottom Line:** Sound Meter - Noise Detector provides a basic utility for casual noise measurement, but its 8-year development silence makes it a legacy tool, so the PM should prioritize a sunset strategy to avoid further brand erosion. **Best for:** Casual users seeking a basic tool to measure environmental noise levels using their mobile device microphone. ### PM Action Plan (Next Best Moves) - [ ] [SUNSET] Sunset the application because the 8-year update drought indicates a lack of viable commercial path → reduce brand drag ### Outlook: Declining The environmental-noise utility market is consolidating around apps with active sensor-calibration updates and high-fidelity visual feedback. Sound Meter - Noise Detector remains exposed due to its lack of development, so the PM should prioritize sunsetting the product to focus resources on higher-yield opportunities. - 🔴 The 8-year update drought indicates the app is in permanent maintenance mode, which prevents it from competing with modern, sensor-calibrated alternatives. - 🔴 Hardware-limited accuracy for sounds over 90 dB creates a functional ceiling that prevents the app from serving as a reliable utility. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 2/5 | | Total Reviews | 5 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 2 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Sound Meter - Noise Detector** (this app) | 2/5 | N/A | 颖 陈 | | [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) | 4.4/5 | Mixed | Fuxin Technology | | [Potatso](https://marlvel.ai/apps/potatso) | 4.4/5 | n/a | Potatso Lab LTD | | [Quantumult X](https://marlvel.ai/apps/quantumult-x) | 3.8/5 | N/A | Cross Utility Ltd | ## Company Profile - **Developer:** 颖 陈 ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/sound-meter-noise-detector/id1150307854?uo=4) - **Sources:** App store metadata. ## Related Intel Reports - [*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) · 4.4/5 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 - [*Sota Connect: Secure Network*](https://marlvel.ai/apps/fi-catconnect-sota) (Cat Connect) · 4.9/5 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 ## 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.
