What you actually get

Two clips of the wallet being used end to end, and four screens from it — the BitMail tampering alert, receiving, coin control, and scanning the chain for the payments only your key can find.

In use
Sending and receiving, start to finish

Screen recordings from the Android build on Signet. No sound.

Sending. Pick a contact by BitMail name, set the amount and fee rate, choose exactly which coins to spend, then review.
Receiving. Scan the chain from the last height you checked, the payment lands, and the transaction opens with its label and explorer link.
Screens
A closer look
A red warning panel reading BitMail tampering detected: the name currently resolves to a different address than your wallet
If a BitMail name stops resolving to your wallet, the app says so before you rely on it — and tells your administrator.
The Receive screen: a QR code for a reusable Silent Payments address, with a form to claim a BitMail name
Your reusable address as a QR — and a BitMail name to put in front of it.
The Coins screen listing unspent coins with amounts, a label action and a freeze button on each
Every coin listed, labelled and freezable. Dust is counted on its own line — unsolicited small coins are flagged and frozen on arrival, so they can't be pulled into a payment and link your wallet together.
The Scan screen showing the chain tip, the height scanned to, and a button to scan the remaining blocks
Scanning the chain for the payments only your key can find.

Screens from the Signet and mainnet builds — identical bar the network they talk to.
