It holds a 4.06/5 rating from 16 reviews. > **Bottom Line:** Roof Guide provides high-utility framing calculations, but its current maintenance-only state limits its competitive longevity. Shifting to a sustainable revenue model would unlock the capital needed to modernize the interface and defend the professional user base against more active rivals. **Best for:** Professional roof framing carpenters, builders, and contractors who require precise, code-compliant construction calculations. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit the current codebase for iOS compatibility because the 8-month update gap risks abandonment by the App Store review process → maintain baseline availability ### Outlook: Declining The construction utility market is consolidating around apps that offer frequent updates and cloud-based project management. Roof Guide's current trajectory is declining due to its lack of active development, which will eventually force professional users to migrate to more reliable, updated alternatives. - 🔴 The 243-day update gap suggests the app is in maintenance mode, which will lead to user churn as competitors release modern, feature-rich updates. - ⚪ The free-only pricing model limits the developer's ability to allocate resources for feature expansion, keeping the app stagnant in a competitive utility market. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.06/5 | | Total Reviews | 16 | | Confidence | Low | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Trend | Declining | | Outlook | Declining | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Roof Guide - Carpentry Calc** (this app) | 4.06/5 | N/A | Infoguide Pty Ltd | | [Sota Connect: Secure Network](https://marlvel.ai/apps/fi-catconnect-sota) | 4.9/5 | 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:** Infoguide Pty Ltd - **Website:** [https://www.infoguide.com.au/roofersguide](https://www.infoguide.com.au/roofersguide) ## Data Sources & Links - **App Store ID:** 920670842 - **Dev Site:** [Official Website](https://www.infoguide.com.au/roofersguide) - **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) · 4.9/5 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 Roof Guide suitable for professional construction work?
