Physical gold & silver portfolio tracker — per-piece cost basis and P/L, offline on your device.

In Development

Portfolio tracker

Track every piece of physical gold and silver you own — weight, purity, premiums, purchase price, and per-piece P/L against spot. Data stays on your device; the API only supplies market prices and comps.

Windows desktop, mobile, and web builds are in private beta. Get in touch if you want access.

Problem

No good way to track a physical precious metals portfolio. Spreadsheets break, existing apps hide data behind paywalls, and none give per-piece cost basis or real-time P/L.

Solution

A privacy-first PM tracker for people who actually hold metal. Log every coin and bar with purchase price, premiums, and storage location. See per-piece profit/loss against live spot, with honest low/mid/high resale estimates from sold-listing data — not hype ranges.

Tech Stack

React Native Mobile app — iOS & Android
Expo Shared codebase; web export planned
SQLite Offline-first — portfolio stays on device
Electron Windows desktop (.exe)
TypeScript
Node.js Spot prices, news, sold-listing comps API
Zustand Local state

Architecture

Client apps (mobile, web, Windows desktop) store your portfolio locally in SQLite. A separate Railway API serves spot prices, FX, news, and market comps only — no user holdings are ever uploaded.

Known Limitations

Web app deploy in progress. Windows desktop and mobile are sideload/private beta. In-app purchases on native builds only.
