US Market. No publisher influence. > **Key Insight:** Concrete Calculator' is a utilities app by Ivan Frolov. ## Quick Facts | Fact | Value | | :--- | :--- | | **Category** | Utilities | | **Developer** | Ivan Frolov | | **Pricing** | Subscription | | **Platforms** | iOS | | **Confidence** | Low (0.2/1.0) | | **Data Age** | 15d | ## Metadata & Market Performance - **Publisher:** Ivan Frolov - **Category:** Utilities - **Target Audience:** DIY enthusiasts and construction professionals needing quick, on-site material volume and cost estimates. - **Platforms:** iOS - **Version Reviewed:** 1.1 - **Report Date:** 2026-09-21 - **Signal Count:** 0 reviews analyzed - **Confidence:** Low (0.2/1.0) - **App Store ID (iOS):** 6468576125 - **Bundle ID:** com.concretecalc.concretecalc - **Data Window:** Analysis based on signals collected up to 2026-09-21 ## Executive Snapshot **What it is:** Concrete Calculator is a masonry utility app for iOS that computes material volumes and project costs based on user-input dimensions. **Why users hire it:** The app removes the manual effort of calculating material requirements for slabs, beams, and columns, which displaces the need for manual guesswork or spreadsheet-based planning. ## App DNA (Features & Intent) - **[Standard] Versatile Concrete Calculators:** Calculates volume for slabs, beams, columns, and staircases based on user-input dimensions. * *User Intent:* Users expect intelligent, adaptive experiences that learn from their behavior. - **[Standard] Concrete Mix Guide:** Provides mix ratios for various project strength requirements, gated behind a $4.99/week subscription. * *User Intent:* Users need clear guidance to understand and adopt the product quickly. - **[Differentiator] Cost Estimator:** Calculates project budget based on user-provided material prices, creating a retention loop for professional users. * *User Intent:* Users seek enhanced value through premium features. ## Market Position {#market-position} Concrete Calculator occupies the professional-utility segment of the masonry market. The lack of updates for 1084 days signals a departure from the active maintenance required to compete with current category leaders. ## Monetization Strategy - **Model:** Subscription - **Tiers:** $4.99 per week - **Analysis:** The subscription model gates all core calculation features, which creates a high barrier to entry compared to ad-supported utility rivals. ## SWOT Analysis {#swot} **Core Strengths:** - Cost estimator creates a financial retention loop **Growth Levers:** - Localized pricing could expand reach in international markets ## What's New - **Latest (v1.1, 2 years ago):** Introduced subscription functionality to the application. ## App Momentum (Zombie) {#momentum} - No updates in 35 months. - Subscription model remains unchanged. > **Cadence:** 1 total versions · 1 majors in last 6 months · 1084 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Concrete Calculator' is an utilities app. > **Bottom Line:** The current subscription-only model and 35-month development freeze invalidate the app's competitive position. Pivoting to a freemium model would unlock the top-of-funnel traffic necessary to compete with active masonry utilities. **Best for:** DIY enthusiasts and construction professionals needing quick, on-site material volume and cost estimates. ### PM Action Plan (Next Best Moves) - [ ] [PIVOT] Pivot to a freemium model because the current $4.99/week gate prevents user acquisition → increase top-of-funnel conversion ### Outlook: Declining Users report: The masonry utility market is shifting toward freemium models that provide basic volume calculations for free, while monetizing advanced structural data. Concrete Calculator's current posture is exposed, as its high entry cost and lack of updates will likely lead to continued stagnation in the face of more agile competitors. - 🔴 The 35-month development freeze signals that Concrete Calculator is in maintenance mode, which erodes user trust and prevents feature parity with active rivals. - 🔴 The $4.99/week subscription gate without a free tier limits the user base, leading to low install velocity compared to ad-supported utility competitors. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Subscription | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Concrete Calculator'** (this app) | N/A/5 | N/A | Ivan Frolov | | [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:** Ivan Frolov - **Website:** [https://apps.apple.com/us/developer/ivan-frolov/id1616814701?uo=4](https://apps.apple.com/us/developer/ivan-frolov/id1616814701?uo=4) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/concrete-calculator/id6468576125?uo=4) - **Dev Site:** [Official Website](https://apps.apple.com/us/developer/ivan-frolov/id1616814701?uo=4) - **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 - [*Track And Field Companion*](https://marlvel.ai/apps/track-and-field-companion) (Travis Menghini) · 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 ## Frequently Asked Questions {#faq} ### Is Concrete Calculator free to use? No, Concrete Calculator requires a $4.99 per week subscription to access all calculation features, including the concrete mix guide and cost estimator. ### How does Concrete Calculator compare to other masonry apps? Unlike many utility apps that offer free basic volume calculations, Concrete Calculator gates all core features behind a weekly subscription, which may be less attractive to casual DIY users. ### Is Concrete Calculator suitable for professional construction work? The app provides volume and cost estimates based on industry standards, but the lack of updates since 2023 means it may not reflect the latest material pricing or structural requirements. ## Methodology {#methodology} This report was generated by Marlvel.ai's 5-stage AI intelligence pipeline: 1. **Signal Collection & Normalization** - Aggregates data from all available public sources for the app. Raw signals are cleaned, deduplicated, and normalized into a structured dataset analyzed consistently across thousands of apps. 2. **Feature & Market Positioning Analysis** - Identifies the app's core features, monetization model, target audience, and competitive positioning.
