The app's free-to-use model targets casual users, positioning it as a lightweight alternative to certified measurement equipment. ## Monetization Strategy - **Model:** Free - **Tiers:** Free with ads - **Analysis:** The app is free to use and monetizes through ad-supported inventory. ## SWOT Analysis {#swot} **Core Strengths:** - Manual calibration tool enables accuracy adjustments for power users **Growth Levers:** - Localized noise-pollution data could provide context to raw decibel readings ## Recent Changes (v2 → v3) {#recent-changes} The product roadmap pivoted from a monetization-first strategy (ad-free tier) to a usability-first strategy (automated calibration) to better serve casual users. The competitive narrative also shifted to explicitly frame the lack of professional certification as a defensive asset against liability. **Overall trend**: Stable **Compared at**: 2026-08-17 ### High-impact changes - **[Shifted] Certification as a Defensive Feature** (positioning) - **[Shifted] Monetization Strategy Pivot** (pricing) ### Medium-impact changes - **[Shifted] SWOT Analysis Update** (swot) ## What's New - **Latest (v2.0.0, 3 weeks ago):** Launched Sound Meter app for real-time decibel (dB) measurement. ## App Momentum (Active) {#momentum} - Launched on iOS and Android July 2026. - Ships bi-weekly stability updates. > **Cadence:** 2 total versions · 1 majors in last 6 months · 14 days since last update · 14 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} Noise Meter - Sound & Decibel is an utilities app that is completely free. > **Bottom Line:** Noise Meter provides a functional reference tool for casual users, but its reliance on device-microphone hardware without professional certification limits its growth potential. The PM should prioritize calibration accuracy to retain the power-user segment. **Best for:** Users needing to monitor noise levels in home, office, or public environments for general reference. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship automated calibration presets because manual tuning is a high-friction barrier for non-technical users → increase retention ### Outlook: Stable The casual noise-monitoring market is currently saturated with free, ad-supported utilities that offer similar core functionality. Noise Meter's ability to maintain its user base depends on the calibration tool's perceived accuracy, as the lack of professional certification prevents it from competing in higher-value, regulated segments. - ⚪ The bi-weekly update cadence indicates a maintenance-focused posture rather than aggressive feature expansion, which limits the potential for rapid market-share gains. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS & Android | | Key Features | 3 analyzed | | Trend | Stable | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Noise Meter - Sound & Decibel** (this app) | N/A/5 | N/A | MINGUK JANG | | [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) | 4.4/5 | Mixed | Fuxin Technology | | [Potatso](https://marlvel.ai/apps/potatso) | 4.4/5 | n/a | Potatso Lab LTD | ## Company Profile - **Developer:** MINGUK JANG - **Website:** [https://safepaln.kr](https://safepaln.kr) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/noise-meter-sound-decibel/id6793926259?uo=4) - **Google Play:** [View on Google Play](https://play.google.com/store/apps/details?id=com.jkcompany.noisemeter&hl=en&gl=us) - **Dev Site:** [Official Website](https://safepaln.kr) - **Sources:** Developer website content, About us / company information, App store metadata. ## 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) · 4.4/5 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 - [*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 Noise Meter accurate enough for professional use?
