The lack of recent updates (6 months) suggests a static market position rather than an aggressive growth strategy. ## Monetization Strategy - **Model:** Free - **Tiers:** Free - **Analysis:** The app is currently offered as a free utility with no visible in-app purchase or subscription gates. ## SWOT Analysis {#swot} **Core Strengths:** - Geometric volume engine standardizes material estimation for complex shapes like stairs and columns **Growth Levers:** - Integration of local material supplier pricing APIs could provide a direct revenue stream ## What's New - **Latest (v1.0.2, 6 months ago):** Maintenance update focused on bug fixes and UI refinements. ## App Momentum (Zombie) {#momentum} - Quiet 6 months, maintenance only. - Last release February 2026. > **Cadence:** 1 total versions · 0 majors in last 6 months · 206 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Concrete Calculator Pro is an utilities app that is completely free. It holds a 4.14/5 rating from 7 reviews. > **Bottom Line:** Concrete Calculator Pro serves as a functional, static utility, but the lack of recent feature expansion leaves it vulnerable to competitors that integrate live material pricing or project management workflows. **Best for:** Contractors, builders, engineers, and DIY homeowners requiring precise material volume estimates for construction projects. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit user retention because the app has been silent for 6 months → determine if the user base is still active ### Outlook: Stable The construction utility market is shifting toward integrated project management tools that include real-time pricing and supplier connectivity. Concrete Calculator Pro remains a static, offline-first tool, which limits its long-term utility as professional workflows migrate to cloud-based platforms. - ⚪ The six-month development gap indicates the product is in maintenance mode, which limits its ability to compete with active, feature-rich rivals. - ⚪ The absence of monetization models prevents the app from funding the infrastructure required to compete with modern, cloud-connected construction tools. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.14/5 | | Total Reviews | 7 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Concrete Calculator Pro** (this app) | 4.14/5 | N/A | Vaghani Keyur | | [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 | | [Fusvob VPN : Super VPN 2026](https://marlvel.ai/apps/com-toplinkc-foxexcellent) | 4.5/5 | Mixed | Fuxin Technology | | [Gear Ratio Calculator & RPM](https://marlvel.ai/apps/cog-gear-ratio-calculator) | N/A/5 | N/A | Linh Phan Nhat Khanh | ## Company Profile - **Developer:** Vaghani Keyur - **Website:** [https://devkrushnaapps.blogspot.com](https://devkrushnaapps.blogspot.com) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/concrete-calculator-pro/id6749880053?uo=4) - **Dev Site:** [Official Website](https://devkrushnaapps.blogspot.com) - **Sources:** Developer website content, 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 - [*Fusvob VPN : Super VPN 2026*](https://marlvel.ai/apps/com-toplinkc-foxexcellent) (Fuxin Technology) · 4.5/5 Rating - [*Gear Ratio Calculator & RPM*](https://marlvel.ai/apps/cog-gear-ratio-calculator) (Linh Phan Nhat Khanh) · N/A Rating - [*NordVPN: VPN Fast & Secure*](https://marlvel.ai/apps/com-nordvpn-nordvpn) (Nordvpn S.A.) · 4.7/5 Rating - [*Pulley Calculator Easy*](https://marlvel.ai/apps/pulley-calculator-easy) (YAVUZ BULAMADIK) · N/A Rating - [*VPN 365-Master WIFI Security*](https://marlvel.ai/apps/vpn-365-master-wifi-security) (vpn fast) · 4.6/5 Rating - [*VPN - Seal VPN Secure Proxy*](https://marlvel.ai/apps/vpn-seal-vpn-secure-proxy) (Starpass VPN Free) · 4.6/5 Rating | Positive Sentiment - [*카톡 분석 - 오픈채팅, 카톡 채팅 분석, 통계, 검색*](https://marlvel.ai/apps/com-liger-katalkanalysispaid) (Park Sung Cheol) · N/A Rating ## Frequently Asked Questions {#faq} ### Is Concrete Calculator Pro free to use?
