## Executive Snapshot
Steam Tables by Carmel Software is a legacy thermodynamic calculation tool for HVAC professionals and students, distinguished by its formula-based engine and interactive slider UI. It currently holds a #87 Paid ranking in the US Business category but faces stiff competition from free industrial-grade apps. The app's 15-year history and integration with an HVAC Equipment Locator provide a unique professional utility that justifies its premium pricing on iOS.

## Rivals Landscape

> Competitive positioning identified by AI analysis of app features, category, and market signals.

### Steam Tables vs TLV Steam Tables — Head to Head
- **TLV Steam Tables** by TLV CO., LTD.: TLV is a global leader in steam engineering, and their app is the primary professional alternative that offers high-precision IAPWS-IF97 calculations for free.
  - **Key differences:**
    - Provides specialized calculations for condensate and flash steam recovery
    - Includes a built-in unit converter specifically for steam engineering parameters
    - Completely free of charge with no ads, backed by a major industrial manufacturer
  - **Publisher (TLV CO., LTD.) strengths:** Global reputation as a 'Steam Specialist' company with deep domain expertise; Strong industrial presence providing hardware and software solutions worldwide
  - **Where Steam Tables wins:**
    - ✅ Interactive slider controls allow for rapid 'what-if' analysis without manual typing
    - ✅ Includes the HVAC Equipment Locator utility as a built-in bonus feature
  - **Where TLV Steam Tables wins:**
    - ❌ Zero-cost entry point compared to the $5.99 premium price of the target app
    - ❌ Direct brand association with industrial steam trap and valve manufacturing
  - **Verdict:** While TLV has the edge in brand authority and price (free), Steam Tables by Carmel Software offers superior interactive utility with its slider-based inputs and broader HVAC-specific toolset for paying professionals.

### Contenders (Strong Challengers)
- **Spirax-Sarco Steam Tables** by Spirax-Sarco Limited: A direct competitor from another top-tier steam engineering firm, providing essential thermodynamic data to the same professional audience.
  - Includes a 'Steam Pipe Sizing' tool within the same interface
  - Features a more technical output display focused on industrial boiler applications
- **Steam Tables - IAPWS-IF97** by Zhenyu He: A highly-rated, utility-focused implementation of the standard steam formulas favored by engineering students and researchers.
  - Focuses on high-precision scientific output for academic use
  - Supports a very lightweight footprint on the device compared to feature-heavy HVAC suites

### Peers (What They Do Better)
- **WolframAlpha** by Wolfram Group: While a general computational engine, it is the go-to tool for engineers to verify complex thermodynamic properties and steam data.
  - Natural language processing allows users to type 'saturated steam at 100 psi' directly
  - Provides graphical representations and step-by-step mathematical derivations
- **Engineering ToolBox** by Engineering ToolBox: A comprehensive reference app that engineers use alongside steam tables for broader material and fluid property data.
  - Covers thousands of materials beyond just water and steam
  - Provides structural and electrical engineering data in addition to thermodynamics

### New Kids on the Block (What's Innovative)
- **Steam Tables Pro** by A-S-T-A: A newer entrant focusing on a modern, dark-mode UI and streamlined mobile experience for the IAPWS-IF97 standard.
  - Highly optimized for the latest iOS versions with a focus on gesture-based navigation
  - Offers a more aggressive update cycle for UI/UX improvements

## The "So What?" (Strategic Takeaway)

Steam Tables is a market-leading business app that is free with in-app purchases.
With a 4.21/5 rating from 1,113 reviews, it delivers strong user satisfaction.

<!-- speakable-start -->
> **Bottom Line:** Steam Tables is a robust legacy tool with a superior calculation engine, but it is resting on its laurels. To defend its #87 ranking against free industrial rivals like TLV, the PM must immediately resolve technical accuracy reports and modernize the output formatting to meet professional standards.
<!-- speakable-end -->

**Best for:** HVAC technicians, engineers, and installers who require precise, on-the-go thermodynamic calculations and equipment management tools.

<!-- section:pm-actions -->
### PM Action Plan (Next Best Moves)

- [ ] [HIGH] Fix scientific notation and exponent readability — *Directly cited as making the app 'useless' in user complaints; critical for professional trust.*
- [ ] [HIGH] Audit kinematic viscosity and Prandtl number calculations — *User reported a 10^6 magnitude error, which is a critical failure for a 'professional-grade' engineering tool.*
- [ ] [MEDIUM] Redesign Android monetization onboarding — *Frequent 'deceptive' labels in reviews indicate the current freemium transition is damaging the brand and driving 1-star ratings.*
<!-- /section:pm-actions -->

<!-- section:feature-gaps -->
### Feature Gaps vs Competitors

- Steam Pipe Sizing tool (available in Spirax-Sarco)
- Condensate and flash steam recovery calculations (available in TLV)
- Dark mode and gesture-based navigation (available in Steam Tables Pro)
<!-- /section:feature-gaps -->

<!-- section:outlook -->
### Outlook: Stable

- 🟢 Android version refactored to Kotlin (v6.2.1) — indicates active technical debt management and platform investment.
- 🔴 Rankings dropped 16 positions to #87 Paid — suggests loss of momentum against newer or free competitors.
- ⚪ Recent iOS updates focused on OS compatibility and basic sharing — maintenance mode rather than feature expansion.
