The lack of updates since the May 2026 release indicates a static product position within the Utilities category. ## Monetization Strategy - **Model:** Free - **Tiers:** Free - **Analysis:** Curtain Calc Pro is distributed as a free utility with no visible in-app purchases or subscription gates. ## SWOT Analysis {#swot} **Core Strengths:** - Geometric coverage engine provides a quantifiable light-blocking ratio that manual methods lack **Growth Levers:** - Integration of a shopping list feature could create a retail conversion funnel ## Recent Changes (v2 → v3) {#recent-changes} The product remains in a static maintenance state, with no functional updates or shifts in monetization. The primary changes involve a more precise definition of the competitive landscape and the removal of localization as a highlighted feature. **Overall trend**: Stable **Compared at**: 2026-08-26 ### Medium-impact changes - **[Added] Competitive Threat Identification** (swot) ### Low-impact changes - **[Removed] Localization Feature Deprioritization** (features) - **[Added] Retail Conversion Opportunity** (swot) ## App Momentum (Maintenance) {#momentum} - Initial release May 2026. - No updates in 99 days. > **Cadence:** 1 total versions · 1 majors in last 6 months · 99 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Curtain Calc Pro is an utilities app that is completely free. > **Bottom Line:** Curtain Calc Pro serves a specific geometric calculation need, but the lack of updates and user feedback suggests a stalled product lifecycle. Establishing a feedback loop or retail partnership would unlock the value of its unique coverage engine. **Best for:** Homeowners and interior design enthusiasts calculating curtain coverage for light control. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Audit user acquisition channels because the app has zero reviews after 99 days → increase visibility ### Outlook: Stable The utility market for niche home-design tools is currently stagnant, with little incentive for users to adopt standalone apps over web-based alternatives. Curtain Calc Pro remains exposed to low discoverability until the developer addresses the lack of community signals and update cadence. - ⚪ The app has remained in maintenance mode for 99 days, suggesting the developer is not actively pursuing user growth. - 🔴 Zero reviews since the May 2026 release indicate a lack of market traction, which limits the ability to iterate based on user needs. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 2 analyzed | | Trend | Stable | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Curtain Calc Pro** (this app) | N/A/5 | N/A | 晓 郭 | | [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:** 晓 郭 ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/curtain-calc-pro/id6770147174?uo=4) - **Sources:** 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 - [*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 Curtain Calc Pro free to use?
