I seem to be the only one that us extremely disappointed with this app. It feels and performs like an IPhone port, which just doesn't work on android at all. I only tinkered with it for 15 minutes before I was forced to refund due to poor performance. I felt the lack of tools (I didn't see a yeast starter calculator, not that the one in the full computer program is that good anyways, no step ups), and no recipe creation ability. Beersmith is a damn fine program so I set my hopes high but for 4 dollars I at least want the ability to scroll without it lagging like crazy.
