The lack of updates for over 2,000 days has resulted in a technical regression that prevents the app from functioning on current operating systems. ## Monetization Strategy - **Model:** Free - **Tiers:** Free - **Analysis:** The app is distributed as a free utility with no observable monetization or in-app purchase gates. ## 🔴 User Sentiment (Low Confidence: 1 of 1 review analyzed) {#user-sentiment} - **Overall Rating:** 2.99/5 - **Platform Split:** iOS 3.0/5 (83 ratings) - **Overall Sentiment:** Frustrated ### Top Complaints (Impact Areas) - **The latest update renders the application unusable on current operating systems for long-term users** ## SWOT Analysis {#swot} **Core Strengths:** - Beaufort scale integration provides a specialized classification layer for maritime users **Growth Levers:** - Localized weather-tracking workflows could be captured if the app were updated to support modern OS standards ## What's New - **Latest (v2.0, 5 years ago):** Launched version 2.0 with a complete redesign for recent iPhone and iPod touch models. ## App Momentum (Zombie) {#momentum} - Dormant for 2048 days. - Last major release February 2021. > **Cadence:** 1 total versions · 1 majors in last 6 months · 2048 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Wind Speed Converter is an utilities app that is completely free. It holds a 2.99/5 rating from 83 reviews. > **Bottom Line:** Wind Speed Converter requires a fundamental compatibility update to restore basic functionality, as the current technical regression is the primary driver of user churn. **Best for:** Users requiring quick wind speed unit conversions for weather tracking or maritime activities. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Rebuild core compatibility for current OS versions because the app fails to launch on modern devices → restore basic utility ### Outlook: Declining The utility category is consolidating around actively maintained tools that integrate with modern OS features. Wind Speed Converter remains in a non-functional state, and without a technical refresh, it will continue to lose its remaining user base to active competitors. - 🔴 The latest version fails to launch on current operating systems, which effectively halts all user activity and prevents new user acquisition. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 2.99/5 | | Total Reviews | 83 | | Sentiment | Frustrated (25/100) | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 2 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Wind Speed Converter** (this app) | 2.99/5 | Frustrated | rapidrabbit | | [Sota Connect: Secure Network](https://marlvel.ai/apps/fi-catconnect-sota) | 4.8/5 | N/A | Cat Connect | | [V2Box - V2ray Client](https://marlvel.ai/apps/v2box-v2ray-client) | 4.6/5 | n/a | techlaim | | [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 | ## Company Profile - **Developer:** rapidrabbit - **Website:** [https://mueller-wulff.de](https://mueller-wulff.de) ## Data Sources & Links - **App Store ID:** 326850907 - **Dev Site:** [Official Website](https://mueller-wulff.de) - **Sources:** App store metadata, User reviews. ## Related Intel Reports - [*Sota Connect: Secure Network*](https://marlvel.ai/apps/fi-catconnect-sota) (Cat Connect) · 4.8/5 Rating - [*V2Box - V2ray Client*](https://marlvel.ai/apps/v2box-v2ray-client) (techlaim) · 4.6/5 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 - [*VPN 365-Master WIFI Security*](https://marlvel.ai/apps/vpn-365-master-wifi-security) (vpn fast) · 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 ## Frequently Asked Questions {#faq} ### Is Wind Speed Converter still being updated?
