If you need a great app for getting your to-do list finished, check out Astid.
At its core, Astrid is a todo list that helps you get stuff done. That’s why Astrid makes it really easy to create lists of tasks, as well as set priority, set due dates, and times.
But Astrid is more than a personal todo list.
Astrid makes it easy to ask for help, delegate and share lists. All your task details are private by default but it is free and easy to share things with as many people as you want.
