I use this as often as I buy, drink or think about beer. (So, not infrequently.) It puts ratings from Untappd, Ratebeer and Beer Advocate in one place, standardizes them to make them comparable to each other, and produces an average rating number that's a great touchpoint. There's also a decent amount of meta-information on each entry, and the index of beers seems limitless (I haven't stumped it yet). I use the iOS app most of all, usually while in a store, but the website's pretty handy too.
