For physical stackers

Your metals.
Your device.
Your eyes only.

Goldfinger tracks every coin and bar you own and values it against live spot prices. Your holdings never leave your iPhone. There is no account to create, because there is no account.

Face ID locked  ·  No analytics  ·  No cloud sync

Locked to your face

Face ID, Touch ID or your passcode is required every time you open the app.

Stays on the device

Holdings sit in on-device storage. There is no cloud sync and no backup server to breach.

Anonymous by design

Price requests carry a random device token. It is not an account, and it is not you.

What it does

Built for those who count in troy ounces.

Every coin and bar

Log weight, purity, quantity, dealer and date. Four Britannias group into one card, not four rows.

Privacy

Your stack never leaves this phone.

There are no accounts, no sign-in and no server holding what you own. The only thing that ever leaves your device is a request for the price of metal, tagged with a random token that is not you. Delete the app and the data is gone, because it was only ever in one place.

Know what your stack is worth.
