It's alright. Its free, so I have no standing to complain. There are run-of-the-mill commercial descriptions of the beers, usually from the brewer's homepage. Just lift the beer out of the sixer and you can probably get the same description. The barcode doesn't work on the iPhone and the food pairings are set for styles and are pretty basic. But again, it's free and I have it and I use it.
I have it and use it now and then. It's okay for being free. I like browsing for beers of a particular style especially while I'm researching for a recipe formulation. I can quickly find commercial examples of a particular style.
