Ultimate Bullion Tracker: a personal bullion tracker.
A practical example of the kind of small software I can build: a tool for keeping useful records on your own computer, with exportable data and no account required for the starter version.
Mac app download
The current supplied build is packaged as a macOS download. It is suitable to keep as a public software example and a starting point for a proper product page.
Clean rebuild for review and install
The source download is a simple Python rebuild. It stores holdings in JSON on the user's computer, accepts manual NZD metal rates, lists holdings, estimates value, and exports CSV.
About this software example.
This page shows how a small owner-controlled tool can be packaged, downloaded, and improved over time. The starter version is intentionally simple so it is easy to review, run, and adapt.
Why it fits the site
Proof that software can be small, useful, and owner-controlled.
This is the same approach I use for custom tools: start with the real workflow, keep the first version understandable, and make sure the owner can get their records out.
Local storage
The starter stores records on the user's computer at ~/.ultimate-bullion-tracker/portfolio.json.
Simple commands
Add holdings, list them, estimate value from manual rates, and export CSV without signing into another service.
Room to grow
A future version could add a desktop interface, charts, backup options, import tools, or optional live price lookups.
