What I really want is a quick tasting notes. Happy Face, Neutral, Sad Face and the ability to easily mark that it was hoppy, tart, heavy, boozy etc. I also want a quick search that lets me quickly record my thoughts & also find my reviews (and other people's) quickly and easily. It might also be cool to have a barcode scanner so I can quickly log my notes by scanning the bottle bar code or check what I thought of a beer by scanning the barcode. That is what I want most out of an app. Aside from that accessing messages, beer trading, and reviews while I'm at a packy to help me make and informed decision would be cool.
