Precision Measurement Architecture

Built specifically to solve the fine weight calculation problem that plagues precious metals investors

Troy Stack calculates melt value using fine weight multiplication, not gross weight estimation. When you add a 22-carat sovereign, the app automatically applies 916.7‰ fineness to derive true gold content. This eliminates the 8% overvaluation error that happens when dealers quote based on total weight.

Every holding entry captures purity, gross weight in your preferred unit (grams, troy ounces, or pennyweight), and the app computes fine metal content instantly. Live spot prices multiply against this fine weight figure to display accurate real-time melt valuation in pounds, euros, dollars, or three other major currencies.

The scrap calculator lets you model mixed-karat scenarios, deduct stone weight from jewelry pieces, and factor in the gap between theoretical melt and actual dealer offers. Purchase cost tracking with premium calculation shows exactly how much over spot you paid on acquisition day, helping identify which dealers offer genuine value versus inflated margins.

Core Functionality Matrix

Fine Weight Tracking

Record holdings by actual precious metal content using fineness multiplication. Supports gold, silver, platinum, and palladium with automatic purity calculation from built-in coin catalogue or manual entry for custom pieces.

Multi-Currency Valuation

Live spot price feeds in six major currencies with timestamp indication. Choose your display currency and the app converts all holdings to show total melt value at current market rates without manual calculation.

Local Encryption

Holdings never touch a server. All data stored on device with optional encrypted backup file protected by your passphrase. Face ID locks the app with configurable timeout from immediate to 15 minutes of inactivity.

Scrap Calculator

Model mixed-karat gold scenarios, deduct stone weight, and calculate the gap between theoretical melt and realistic dealer offers. Essential for evaluating jewelry or damaged coin lots before selling to refiners.

Purchase Premium Analysis

Record original cost with postage and VAT. App calculates premium over melt on purchase day and tracks per-ounce pricing across different dealers to identify which sources offer consistent value versus inflated margins.

Application Philosophy

Troy Stack operates as a personal ledger, not an investment adviser. No buy signals, no price predictions, no market recommendations. The app displays melt value (metal worth at spot) which differs from dealer purchase prices due to premiums and market conditions. This is a private record-keeping tool for individuals who understand precious metals markets and require accurate fine weight calculation without cloud exposure.
