It lets you sort and filter tasks according to a set of options and priorities you can set and change anytime. You can also set it to send you daily or weekly “digests” which are summary messages based upon the data you enter. You can also share and assign tasks with another Astrid user.
Astrid is open-source and free. It saves all your data in the “cloud” and lets you synchronize between your Astrid account, Google Tasks, and an iPhone or Android mobile."
bTodo does let you set up more than one user for a single account, so it is well suited for collaborative teams. If you want a simple, online task manager and you don’t want to spend a lot of time learning a new user interface, give this a test drive. You might like it."
With this app you make yourself little bulletized “to-do” lists that look like tweets — they even have hash tags! You can display them sequentially, a day or a week’s worth, by date or by category. You can set the app to send you reminders, if you like, by IM or email. It synchronizes with various other applications including Google Calendar and Microsoft Outlook.
This is one of those odd, love-it-or-hate-it apps. It’s the product of a sole Brazilian developer who asks for a donation if you love it. You just might."
