Accomplice

Accomplice™ is a software application that helps busy professionals like you manage your to-dos, goals, and notes, then sync them with your team.
This isn’t some trivial to-do list, and it isn’t an overweight project management suite.

Accomplice has just the ingredients you really need to stay on top of your busy life, integrated into an intuitive and flexible system.
It works online and offline, integrates with Outlook and other software you already use, and syncs with your PDA.
