Added Beersmith2 for IPadl and see this as a very nice "companion" app to the full version. It is great on brew day, nice to edit and adjust recipes, and perfect to take with me to the LB shop.
It is not a replacement of the full version. My feeling is that is that Ibrewmaster is the way to go if you are looking for one all around mobile brewing software. If you want (I do) the most feature rich brewing software available along with a solid mobile companion, original BeerSmith and mobile BeerSmith are your babies.
