Having trouble keeping track of staff? Given up on in/out boards?
Then you might want to try APT (Automated People Tracker), a
lightweight client/server application for Macs and PCs featuring a
unique call-back facility written in REALbasic.

Available from http://homepage.mac.com/robinmh

Clients are available for both the Mac and PC with the server
component having been tested on the Mac. It features an easy set up
process (local customisation is in a file that accompanies the
client).
