The guided demo runs on sample data in your browser — nothing is connected to a production system and no real transaction is processed. Where a real URL can be framed, the toolbar above switches to it and says so.
Capabilities you could commission.
An optional app lock built on the device biometric API — Face ID, Touch ID or Android biometrics — with a passcode fallback and a settings toggle.

People holding precious metal have no idea what it is worth today, and the answer depends on weight, purity and a spot price that moves every minute.
A calculator that gets the arithmetic right — troy ounces, karat purity, live spot — plus a stack tracker that values a whole collection at once.
The implementation, at a level we can share.
- ✓Melt value stated as melt value, with an explicit note that dealers pay below it
- ✓Purity handled as a factor rather than a label, so 18k is 0.750 everywhere
- ✓Live metals pricing from a third-party feed — a recurring cost the client owns
- ✓Stack tracking that revalues every holding when spot moves
