Perly · four products, one sea

Your bitcoin, the market, and what you are paid.

A private ledger for what you hold, a free board of the market, invoices paid your way, and payments straight to your own wallet — each its own product, and none of them asks for your keys.

What it cost, and what it is worth.

Cost basis, profit and return, worked out from every buy and sell you record — in dollars, or in bitcoin.

The app's own screens, rebuilt from its code and set in motion, on the demo portfolio at real market prices.
