We have released our cupping calculator and made it free for everybody: cupscore.lafamiliacafe.co. It runs in a browser, so there is nothing to download and no licence to buy.
You cup alone or with a table, one lot or up to twenty in a session. Your tasters join by typing a code or scanning a QR, so they install nothing and register nothing. You watch the scores build live, then get a PDF report in the language of whoever opens it. Descriptors come from the interactive flavour wheel and stay attached to the attribute you tasted, every session is kept in one history, and nothing is lost if the signal or the phone gives out. Both the classic SCA form and the Coffee Value Assessment are supported.
Try it, then tell us what is missing: info@lafamiliacafe.co, with "Cupscore" in the subject line.
