Gold and silver stack tracker
Log every coin, round and bar with its weight, purity and what you paid. OunceTray adds up the fine ounces of each metal, shows the melt value at the latest spot price and works out the premium you paid over spot.
$29.99 ONCE · $14.99 A YEAR · $2.99 A MONTH
Silver, gold, platinum and palladium each add up in large figures, in troy ounces or grams, with the melt value at the spot price shown and the change since the last saved price. One tap hides the amounts, so you can show someone your stack without showing what it cost or what it is worth.
Record the metal and form (coin, round or bar), name, mint, year, weight, purity, quantity, price paid per piece, purchase date, dealer, storage location, tags, notes and up to six photos. The fine metal shows as you type, so you can check it before saving.
Start from an American Silver Eagle, a Maple Leaf, a Britannia, a Krugerrand, a Sovereign, 90% US silver by face value or a bar from 1 oz to 1 kg, and the weight and purity are set for you.
OunceTray keeps the daily spot prices it fetches, so a coin added on the day you buy it gets that day’s spot when the app has fetched it. The premium is worked out per piece and averaged per metal by ounces. If the price paid or that day’s spot is missing, the premium shows as unknown rather than zero.
Record part or all of a holding sold, with what you received and the fees. The sold list shows the gain or loss against what those pieces cost, and the rest stays in your stack.
A PDF with each piece’s photo, weight, purity, fine metal, price paid and purchase date, plus totals per metal, for a home insurance policy or a safe deposit record. A CSV of the inventory for your own spreadsheet.
There is no account. Your inventory and photos stay on your phone; when the app fetches spot prices, your holdings are not sent with the request. Backup makes one file you can restore on another phone.
The app checks for a new spot price once a day and shows where it came from and when. Without a connection it uses the last saved spot price, and you can type a price at any time.
OunceTray does not buy, sell or hold metal, appraise coins or give financial or tax advice. Melt value is weight times the spot price shown, not an offer. Collector value is not included.
Up to 30 holdings with the stack screen, spot prices, search, photos, sharing and backup. A banner ad shows on the Holdings and Sold lists, never on the stack screen.
An optional 14-day trial is offered in the app; it starts only when you tap it.
No ads with the full tray.

No. It shows melt value, the metal content times the spot price shown. Collector value is not included.
Yes. Switch between troy ounces and grams in Settings. Weights can be entered in ounces, grams or kilograms.
Every holding stays readable and editable. Past 30 holdings, adding more needs the full tray again.
No. There is no account and your holdings stay on your phone. Crash reports and app usage statistics are sent, and neither carries your holdings.
Yes. Back up to one file from Settings, then restore it on the new phone. Restoring adds what is missing and deletes nothing.
Add your first coin from a common piece and see its fine ounces before you save.
