The lack of recent major feature updates suggests a maintenance-only posture that limits its competitive reach against more active professional tools. ## Monetization Strategy - **Model:** Free - **Tiers:** Free - **Analysis:** The app is distributed as a free utility with no visible subscription or in-app purchase gates. ## 🟢 User Sentiment (Medium Confidence: 1 of 1 review analyzed) {#user-sentiment} - **Overall Rating:** 4.1/5 - **Platform Split:** iOS 4.1/5 (10 ratings) - **Overall Sentiment:** Excited ### Top Praises - **High-quality graphical rendering provides a clear visual check for condensation potential in building assemblies** ### Top Complaints (Impact Areas) - **Inability to save custom wall constructions prevents users from building a library of typical assemblies** ## SWOT Analysis {#swot} **Core Strengths:** - Graphical dew point visualization provides a clear visual check for condensation potential **Growth Levers:** - Integration of imperial units for material creation would improve professional workflow usability ## What's New - **Latest (v1.5.1, 1 weeks ago):** General bug fixes and stability improvements. ## App Momentum (Maintenance) {#momentum} - Ships bug fixes every few months. - No major feature updates recently. > **Cadence:** 2 total versions · 0 majors in last 6 months · 7 days since last update · 208 days avg between updates ## The "So What?" (Strategic Takeaway) {#so-what} Thermal Transmittance Calc is an utilities app that is completely free. It holds a 4.1/5 rating from 10 reviews. > **Bottom Line:** Implementing assembly-saving functionality would address the primary friction point preventing professional adoption. This investment would transition the tool from a simple quick-check utility to a persistent workflow asset for insulation planning. **Best for:** Construction professionals and homeowners planning building insulation or facade improvements. ### PM Action Plan (Next Best Moves) - [ ] [INVEST] Ship assembly-saving functionality because it is the top-requested missing feature → unlock professional adoption ### Outlook: Stable The specialized utility market for construction planning is consolidating around tools that offer persistent project libraries and flexible material management. Thermal Transmittance Calc remains stable but exposed, as the lack of assembly-saving features will likely drive power users toward more comprehensive professional alternatives. - 🔴 The maintenance-only release cadence prevents feature expansion, which risks losing users to more active professional tools that offer library-saving capabilities. - 🟢 High-quality graphical rendering for condensation analysis remains a strong differentiator that retains the current user base despite the lack of updates. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Overall Rating | 4.1/5 | | Total Reviews | 10 | | Sentiment | Excited (70/100) | | Confidence | Medium | | Pricing Model | Free | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Thermal Transmittance Calc** (this app) | 4.1/5 | Excited | ALEXEY KOZLOV | | [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:** ALEXEY KOZLOV - **Website:** [https://ak-develop.com](https://ak-develop.com) ## Data Sources & Links - **App Store ID:** 1473745621 - **Dev Site:** [Official Website](https://ak-develop.com) - **Sources:** Developer website content, About us / company information, App store metadata, User reviews. ## 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 - [*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 - [*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 Thermal Transmittance Calc suitable for professional construction planning? While the app provides useful quick-check graphical condensation analysis, users report that the lack of assembly-saving features and rigid material management limits its utility for complex professional workflows. ### Does the app allow me to save my wall constructions? No, current user feedback indicates that the app does not support saving custom wall constructions, which prevents users from building a library of typical assemblies for future reference. ### Can I use imperial units in this app? The app supports input toggling for dimensions in inches, but users have requested more detailed imperial unit support for new material creation to improve usability. ## 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.
