From the developer:
This application helps you manage several bat recordings easily. The program sometimes calculates stuff in the background while you are in the foreground. The batIdent results are imported automatically if you wish. Using the built-in report functions you can summarize data of multiple nights of your sampling scheme and extract number of contacts.
