The app has a very basic interface. You enter information for each cow, and the system calculates how many animals you need to replace to maintain herd size and produce milk/calves. Then, if you wish, you can export the results to other software packages such as Microsoft Excel or Word. I like being able to download an excel spreadsheet of all my data. In addition it would be cool to see graphs over time showing how much profit I make from this program compared to last year. Also, exporting cows into a different breed might help me decide which one I want to use next season. Overall though, it was pretty useful!
