TabTether

TabTether is a mobile app for groups on a night out to track shared spending in real time and settle instantly—without relying on one “designated payer.” Users create a night “tab,” add friends via link/QR, and log items quickly (or import receipts). The app calculates splits by item, percentage, or custom rules (e.g., “Alex covers shots,” “everyone splits rides”). It supports instant settlement through connected payment rails and includes a tip assistant that suggests fair tips based on venue type and local norms. For venues and promoters, TabTether offers optional event links and group incentives (e.g., “settle your tab to unlock a drink special”), but the core value is consumer-first: reduce friction, reduce arguments, and keep the night moving. Realistically, adoption hinges on making setup faster than Venmo notes and easier than spreadsheets.
