US Market. No publisher influence. > **Key Insight:** Reaction Thermodynamics is a education app by Roman Volinsky. ## Quick Facts | Fact | Value | | :--- | :--- | | **Category** | Education | | **Developer** | Roman Volinsky | | **Pricing** | Paid | | **Platforms** | iOS | | **Confidence** | Low (0.2/1.0) | | **Data Age** | 12d | ## Metadata & Market Performance - **Publisher:** Roman Volinsky - **Category:** Education - **Target Audience:** Chemistry students and professionals requiring specialized thermodynamic and stoichiometric calculation tools. - **Platforms:** iOS - **Version Reviewed:** 3.6 - **Report Date:** 2026-09-18 - **Signal Count:** 0 reviews analyzed - **Confidence:** Low (0.2/1.0) - **App Store ID (iOS):** 1090321476 - **Bundle ID:** com.appleVR.Thermodynamics - **Data Window:** Analysis based on signals collected up to 2026-09-18 ## Executive Snapshot **What it is:** Reaction Thermodynamics is a specialized education app for chemistry students and professionals that calculates thermodynamic parameters and equilibrium constants on iOS. **Why users hire it:** The app removes the manual friction of multi-step thermodynamic calculations by automating formula-based solving for standard and non-standard energy parameters. ## App DNA (Features & Intent) - **[Standard] Thermodynamic Parameter Calculation:** Calculates standard Gibbs energy, enthalpy, and entropy based on formation energy parameters. - **[Differentiator] Van't Hoff Relation Calculator:** Models changes in equilibrium constant relative to temperature shifts, reinforcing academic authority. - **[Differentiator] Data Interoperability:** Allows transfer of initial data from the Stoichiometry app to calculate gaseous compound pressures and volumes. ## Market Position {#market-position} Reaction Thermodynamics occupies a niche segment of the Education category, relying on a $3.99 one-time purchase model. The lack of updates for 24 months suggests a static market position that prioritizes long-term utility over active growth. ## Monetization Strategy - **Model:** Paid - **Tiers:** $3.99 one-time purchase - **Price:** iOS: $3.99 - **Analysis:** The $3.99 one-time purchase model targets students and professionals seeking a specialized, ad-free academic tool. ## SWOT Analysis {#swot} **Core Strengths:** - Data interoperability with Stoichiometry suite creates specialized academic workflow **Growth Levers:** - Localized pricing could capture students in high-ARPU markets ## What's New - **Latest (v3.6, 2 years ago):** General compatibility update. ## App Momentum (Zombie) {#momentum} - Ships no major updates since 2024. - Maintains static feature set for years. > **Cadence:** 1 total versions · 0 majors in last 6 months · 739 days since last update ## The "So What?" (Strategic Takeaway) {#so-what} Reaction Thermodynamics is an education app that is a paid app. > **Bottom Line:** Reaction Thermodynamics maintains a stable position as a niche academic tool, but the two-year release gap risks obsolescence as student expectations for mobile academic software shift toward more integrated, frequently updated platforms. **Best for:** Chemistry students and professionals requiring specialized thermodynamic and stoichiometric calculation tools. ### PM Action Plan (Next Best Moves) - [ ] [MAINTAIN] Audit formula library because the 24-month update gap risks academic relevance → maintain user trust ### Outlook: Stable The academic utility market is consolidating around platforms that offer frequent updates and broader integration. Reaction Thermodynamics remains stable due to its niche focus, but the lack of recent releases leaves it exposed to more dynamic academic competitors. - ⚪ The 24-month release gap indicates a maintenance-only posture, which limits growth but preserves the app's core utility for existing users. ## Key Metrics Summary | Metric | Value | | :--- | :--- | | Total Reviews | 0 | | Confidence | Low | | Pricing Model | Paid | | Platforms | iOS | | Key Features | 3 analyzed | | Outlook | Stable | ## Competitor Comparison | App | Rating | Sentiment | Developer | | :--- | :--- | :--- | :--- | | **Reaction Thermodynamics** (this app) | N/A/5 | N/A | Roman Volinsky | | [Catbus Student](https://marlvel.ai/apps/catbus-student) | 4.3/5 | N/A | Cohota Join Stock Company | | [Money Matrix (CAD)](https://marlvel.ai/apps/money-matrix-cad) | 5.0/5 | N/A | Blooming Kids Software LLC | | [Quran Treasure Island for Kids](https://marlvel.ai/apps/quran-treasure-island-for-kids) | 4.9/5 | Mixed | Akeela Manekia | | [Valencia College - MyVC](https://marlvel.ai/apps/valencia-college-myvc) | 5.0/5 | N/A | Valencia College | | [Verbi: Learn a New Language](https://marlvel.ai/apps/verbi-learn-a-new-language) | 4.3/5 | n/a | ACADIA LABS INC. | ## Company Profile - **Developer:** Roman Volinsky - **Website:** [https://www.volard.wordpress.com](https://www.volard.wordpress.com) - **Social:** [Facebook](https://www.facebook.com/sharer/sharer.php?kid_directed_site=0) · [X/Twitter](https://twitter.com/intent) ## Data Sources & Links - **App Store:** [View on Apple Store](https://apps.apple.com/us/app/reaction-thermodynamics/id1090321476?uo=4) - **Dev Site:** [Official Website](https://www.volard.wordpress.com) - **Sources:** Developer website content, App store metadata. ## Related Intel Reports - [*Catbus Student*](https://marlvel.ai/apps/catbus-student) (Cohota Join Stock Company) · 4.3/5 Rating - [*Money Matrix (CAD)*](https://marlvel.ai/apps/money-matrix-cad) (Blooming Kids Software LLC) · 5.0/5 Rating - [*Quran Treasure Island for Kids*](https://marlvel.ai/apps/quran-treasure-island-for-kids) (Akeela Manekia) · 4.9/5 Rating - [*Valencia College - MyVC*](https://marlvel.ai/apps/valencia-college-myvc) (Valencia College) · 5.0/5 Rating - [*Verbi: Learn a New Language*](https://marlvel.ai/apps/verbi-learn-a-new-language) (ACADIA LABS INC.) · 4.3/5 Rating - [*자주 틀리는 우리말*](https://marlvel.ai/apps/app--424) (DaolSoft, Co., Ltd.) · N/A Rating - [*달공부 - 한 달 공부 다이어리 + 루틴/공부 타이머*](https://marlvel.ai/apps/azlabs-dalstudy) (SuWon Choi) · N/A Rating - [*타요콘 - 타요 아바타 놀이동화*](https://marlvel.ai/apps/com-kigle-project-tayocon) (KIGLE) · 3.1/5 Rating - [*천자문 워치*](https://marlvel.ai/apps/app--385) (kim juyoung) · N/A Rating - [*천자문 공부 도우미*](https://marlvel.ai/apps/app--382) (kim juyoung) · 5.0/5 Rating ## Frequently Asked Questions {#faq} ### Is Reaction Thermodynamics suitable for university chemistry courses?
