Dropzball makes focused add-ons, spreadsheets and planners that each do one thing well. Watch a short demo of each one, then try it.
Dropzball is run by Yaël Serfaty, who writes literary fiction as SOLOMON. The author tools are built for the same steps he goes through with his own books: formatting, submission and print.
