JIRA-sync is a nifty little tool to get a delta between a given (past) date and the current version of a JIRA Scrum Board.
Are you a Scrum Master or someone who really tries to synchronize a JIRA board to a physical board? Don't get frustrated checking each card, use this tool to help you using your other tool. Like that Agile Manifesto tells us: We value processes and tools over individuals and interactions. Or something similar.
Sign in with your JIRA Credentials (they are not stored on the server, rather on the client in an encrypted Cookie), select a board and a date and get changes to update your physical board accordingly.
