If you are unable to find your favorite sip among those in the database, feel free to add it yourself. You can also proof and edit others' publications for factual correctness. Beered! also mixes in "awesome beer facts",lists of your favorite beers, and beers you've read about before. To top it all, the app looks great in Microsoft's design language.
Although Beered! is pretty much like Wikipedia for brews, it cannot be referred to as "the free beercyclopaedia", because it costs $0.99. Still, if you are writing an academic study on beer, or want to impress your peers with an immaculate knowledge on the subject, you'll obtain a lot of resources for the sum.
