Just excellent. This is the only app Ive ever paid for! When Im out with friends trying new beers its especially helpful because I can keep track of what Ive had and have a better idea of when its time to go home! Get it. Its worth it!
The only thing I would change is to have the drink list be alphabetized or in numerical order when you open the app. Instead, when you add a new drink it puts it at the bottom of the list. After you drink that drink, its at the top of the list, which is great. But all the drinks are just seemingly in no kind of order otherwise.
