CupTally

CupTally is a lightweight utility for tracking communal coffee consumption on shared bean-to-cup machines, designed to replace informal cash jars and ad‑hoc sheets. The app records location details, users and active coffee bags in an online database managed through a web admin interface, and lets members register on their devices with a unique code. Consumption is logged in real time from both mobile and web, and when a bag is closed CupTally calculates the average price per cup and assigns payment obligations automatically. Communities use it to make billing transparent, simpler and fairer without manual tallies.
