Untappd

Untappd is a free application for iOS and Android that lets users log and rate beers, wines, spirits and other drinks, building a personal drink journal and unlocking badges for trying new items. It also surfaces nearby bars, restaurants, bottle shops, breweries and wineries, showing what each place currently has available and sending notifications when new drinks appear at followed venues. For business owners, the platform builds menus that combine beer, wine, liquor and food, publishing them to a website, digital signage and the Untappd app itself, alongside data on drink trends in an area and tools to interact with customers through check-ins and events. The site states its menu tools are used by nearly 20,000 retailers across 75 countries.

Untappd's ads.txt file lists 122 ad system lines, with 60 direct and 102 reseller entries, naming Freestar LLC, Vuukle DMCC, Advally, Seedtag and Smile Wanted among its sales houses.
