Brewzor is a very handy app, and is being worked on and updated weekly.. Even if we never saw a BeerSmith android app, I think that between these two developers we could get a very smooth transition with the export/import features to use our phones on brew day for changes and etc...
The application has the ability to bring in "database" items such as hops/grains/yeast etc, and if it was linked correctly with beersmiths defaults this could help the average beersmith user to see simular results across the two platforms.
