SYGNout, part of the SYGNAL broadcast toolkit, tracks comms kit on a show: which beltpack, panel and headset is out to whom, checked out and back in by barcode from a scanner on the laptop or a phone camera.

This installs a small menu bar app that runs the SYGNout server on this Mac. From the SYGNout icon in the menu bar (signal arcs with an arrow) you can open it in your browser, connect a phone, start, stop or restart it, change its ports, see its log and any errors, make a backup, and have it open when you log in.

Data lives in ~/Library/Application Support/ComsLogger. Installing over an older copy keeps it. That folder keeps the app's old name, Coms Logger, and this installer replaces an app of that name with this one.
