The lack of recent updates (134 days since last store activity) signals a maintenance-only posture that limits competitive growth. ## Monetization Strategy - **Model:** Free - **Tiers:** Free access to all core analysis features - **Analysis:** The app operates as a free utility with no visible subscription or IAP gates, limiting its ability to fund ongoing development. ## SWOT Analysis {#swot} **Core Strengths:** - Visual Proportion Map provides immediate feedback on facial alignment **Growth Levers:** - Monetization via premium analysis tiers could fund future development ## What's New - **Latest (v8.3, 4 months ago):** Platform update focused on performance and stability improvements. ## App Momentum (Maintenance) {#momentum} - Ships only stability and performance updates - Four months without feature expansion > **Cadence:** 1 total versions · 0 majors in last 6 months · 133 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Golden Ratio DIY is an utilities app that is completely free. It holds a 3.01/5 rating from 69 reviews. > **Bottom Line:** Golden Ratio DIY provides a functional facial-proportion utility, but its maintenance-only posture risks long-term relevance. Introducing a monetization tier would unlock the capital needed to compete with more active beauty-tech rivals. **Best for:** Users interested in facial aesthetics and mathematical proportion analysis. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship a social-sharing export flow because the current lack of viral loops limits acquisition → increase organic install velocity ### Outlook: Declining The beauty-tech utility market is consolidating around apps that offer frequent feature updates and social integration. Golden Ratio DIY remains in maintenance mode, which will likely lead to a decline in user engagement as more dynamic competitors capture the market share. - 🔴 The 134-day update gap indicates a lack of active development, which erodes user trust in the app's long-term utility. - ⚪ The current free-only model fails to capture value from the core user base, leaving the app without a clear path to sustainability. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 3.01/5 | | Total Reviews | 69 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 4 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Golden Ratio DIY** (this app) | 3.01/5 | N/A | Ming Hei Tsui | | [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:** Ming Hei Tsui - **Website:** [https://www.purplefarm.link/privacy_golden_ratio_pro](https://www.purplefarm.link/privacy_golden_ratio_pro) - **Social:** [YouTube](https://www.youtube.com/playlist) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/golden-ratio-diy/id1467153331?uo=4) - **Dev Site:** [Official Website](https://www.purplefarm.link/privacy_golden_ratio_pro) - **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) · 4.8/5 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 Golden Ratio DIY accurate for measuring beauty?
