Snap the receipt. Everyone pays their part.
Tabby is for the moment after a group dinner, a ski trip, or a shared grocery run, when one person has paid for everyone and now has to collect. The host snaps the receipt (or just says what everyone had), friends scan a QR code, tap what was theirs, and pay their exact share in about a second. Payments settle on Solana, every one carries an on-chain receipt, and the bill stamps itself Settled when the last person pays.
No app to install, no accounts, no math, no chasing.
