With iGTD different schedule tasks in different contexts and projects can be planed. These objects can be created easily and assigned with a description and priority.
The software offers a lot of other features. You can synchronize everything with iCal, a PDA or iPod. A plugin for Quicksilver simplifies working and a iBackup plugin allows quick and easy creation of backups.
Since version 184.108.40.206 iGTD is no longer being developed. The developer is now working on commercial alternative Things.
