Why Bullio exists
Spreadsheets aren't a portfolio tracker.
Existing apps treat physical metals like digital tickers. No proper lot pooling. No purity-aware weight maths. No realised P&L. Most send your data to servers you've never heard of.
Bullio is built by a stacker, for stackers. Your portfolio lives in a local SQLite database on your phone. Our server exists for one purpose: to cache spot prices. It never sees your holdings.
Features
Every feature a serious stacker needs.
Premium
Sales, realised gains & tax-time reports.
Every sale's profit and loss, realised gain over time, per-metal breakdown, best/worst and win-rate — then export a realised-gains report tuned to your country.
Country-aware reports: AU · US · UK · CA · DE
Correct financial-year boundaries & holding-period rules
A record-keeping aid — general info, not tax advice
Insight
Charts that tell you something.
Stack value over time, allocation by metal, and cost basis versus spot — designed for clarity, not default chart-library output.
Allocation by metal — by value or weight
Cost basis vs spot, per metal
Buy & sell markers along your timeline
Premium
Alerts that watch the market for you.
Set a target price, a percentage move, or a break-even alert per metal — checked privately on your device and delivered as a notification.
Target price, % change, or break-even
Evaluated on-device — thresholds never leave your phone
Premium
What-If, before you buy or sell.
Punch in a hypothetical gold or silver price and instantly see what your whole stack would be worth — across the dashboard, holdings and charts.
Model a price target without touching your records
Live across the dashboard, holdings and charts
Purity-aware
Every lot, to the fine ounce.
Open any holding for fine-weight value, cost vs spot per coin and per kg, lifetime realised P/L, and its full buy/sell history — calculated, never estimated.
True fine weight for 22ct coins and .9999 bars
Unit counts for coins and bars — total owned and per purchase
Per-coin and per-kg cost vs live spot
Lifetime realised P/L and every transaction
Privacy
Read our full privacy policy
Your portfolio never leaves your device.
Bullio's backend does two things: serve spot prices and validate your subscription. That is all it does.
No account required. There is nothing to sign up for and nothing to breach.
All financial data — holdings, transactions, realised P&L — lives in a SQLite database on your phone.
The Metals.Dev API key lives on our server.
Your app never sees it.
Security
Your stack stays yours.
Your data is encrypted on your device. Only you hold the key — we can't read it, and neither can anyone else without it.
Add an optional passphrase for a second layer only you know. There is no backdoor and no recovery path.
Backups are zero-knowledge: encrypted with your passphrase before they leave your device. Even Bullio cannot read a backup file.
