I think the "big money" would be in developing the whole back-end stock control software and licensing that to the breweries - the fact that it allows the use of mobile app is an added selling point; not only could customers see if their favourite ale is available but the company execs/regional managers would have a world of data at their fingertips.
Again I'm sorry you're dissapointed; I can only ask you to bear with it unitl it becomes something magical, buesides if you're that hard up for 69p perhaps you shouldn't have an iPhone.
I've already made enquiries into porting to andriod, I had intended to hire a programmer to do the port, but I only wanted to do it the once - i.e. when the app was ready.
I chose the iPhone primarily because it was the device I own and the consistancy across the IOS devices - I'm led to believe they're a lot of fragmentation across the android range.
