<!-- section:executive-snapshot -->
## Executive Snapshot
**What it is:** Material Weight Calculator is a productivity utility for estimating the weight of Aluminum, Steel, and Copper components.
**Why users hire it:** Users hire this tool for quick, low-stakes metal weight estimations, but the lack of updates forces power users toward more comprehensive engineering suites.
<!-- /section:executive-snapshot -->

<!-- section:features -->
## App DNA (Features & Intent)
- **[Basic] Material Weight Calculation:** Calculates weight based on material type, currently supporting Aluminum, Steel, and Copper.
- **[Basic] Keyboard Dismissal:** Closes the on-screen keyboard when the user touches outside of active text fields.
<!-- /section:features -->

<!-- section:market-position -->
## Market Position {#market-position}

The app maintains a 5-star rating on a single review, reflecting its legacy status as a static utility without recent market activity.
<!-- /section:market-position -->

## Monetization Strategy
- **Model:** Free
- **Tiers:** Free
- **Analysis:** The app is distributed as a free utility with no observable monetization or in-app purchase gates.

<!-- section:swot -->
## SWOT Analysis {#swot}

**Core Strengths:**
- Zero-friction free utility model attracts hobbyist users.

**Critical Frictions:**
- No feature updates since 2014.
- Limited material library.
- No monetization strategy.

**Growth Levers:**
- Expand material library to include common alloys.
- Integrate unit conversion tools.

**Market Threats:**
- Competitors bundling multiple trade calculators.
- Platform-level deprecation risk.

<!-- /section:swot -->
## Recent Changes (v2 → v3) {#recent-changes}

The competitive landscape was updated to focus on specialized industrial engineering tools, and the outlook was downgraded to declining due to the lack of maintenance.

**Overall trend**: Declining
**Compared at**: 2026-05-26

### High-impact changes
- **[Shifted] Competitive Landscape Overhaul** (positioning) — Replaced general-purpose competitors (Unit Converter) with specialized industrial tools (MyHSRC, Bearing, Vibration analysis, Vibrochecker, Build Specs, GearCalc Pro).
- **[Shifted] Threat Profile Update** (swot) — Threats shifted from horizontal utility apps to platform-level deprecation risk and specialized trade calculator bundling.

### Medium-impact changes
- **[Declined] Outlook Trend Downgrade** (positioning) — Outlook trend moved from stable to declining, citing increased risk of invisibility to platform discovery algorithms.
- **[Shifted] Strategic Pivot Recommendation** (positioning) — PM action item changed from expanding the material database to pivoting toward a multi-tool engineering suite.

<!-- section:whats-new -->
## What's New

- **Latest (v1.0.1, 11 years ago):** Keyboard now dismisses when tapping outside of text fields.
<!-- /section:whats-new -->

<!-- section:momentum -->
## App Momentum (Zombie) {#momentum}

- No feature updates since 2014.
- Stagnant product lifecycle.

> **Cadence:** 1 total versions · 0 majors in last 6 months · 4371 days since last update

<!-- /section:momentum -->

<!-- section:so-what -->
## The "So What?" (Strategic Takeaway) {#so-what}

Material Weight Calculator is an established productivity app that is completely free.
With a 5/5 rating from 1 reviews, it shows polarized user reception.

<!-- speakable-start -->
> **Bottom Line:** The app serves a narrow utility but lacks the update cadence to remain relevant, so the PM should pivot toward a multi-tool engineering suite to avoid total obsolescence.
<!-- speakable-end -->

**Best for:** Professionals or hobbyists requiring quick weight estimations for common industrial metals.

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

- [ ] [PIVOT] [MEDIUM IMPACT] Pivot to a multi-tool utility because competitors bundle trade calculators → capture broader engineering audience — *Competitors like Build Specs bundle multiple trade tools, making a single-function calculator obsolete.* _(trade-off: deprioritize Pause maintenance of the current weight-only logic — the current tool is already in maintenance mode.)_
<!-- /section:pm-actions -->

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

- Dimensional search (available in Bearing)
- FFT and PSD signal analysis (available in Vibration analysis)
- 3D gear train simulation (available in GearCalc Pro)
<!-- /section:feature-gaps -->

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

The engineering utility market is consolidating around multi-tool suites that integrate simulation and procurement, leaving single-function calculators like this one exposed. Without a shift to a broader feature set, the app will continue to lose relevance to modern, active competitors.

- 🔴 The lack of updates since 2014 signals a stagnant product lifecycle, which erodes discoverability against active engineering competitors.
