Astrid Tasks is a combination task manager/to do list/personal assistant--it's like the personal secretary you never had. Although its primary user base is likely to be people who are already using their mobile devices for personal tasks, this is one of those apps that will convince you that smartphones and tablets are not just for making calls, listening to music and watching videos.
Astrid is all about making your life easier through organization. The app lets you create reminders, lists, subtasks and widgets. By using the app, which automatically synchronizes tasks via a cloud server that runs on Astrid.com, you can access their updated lists and notes using your tablet, phone or other mobile device.
