Taska is a GTD app with very easy-to-use features. Create and manage todo's, lists, contexts, and tags. There's even a built-in map to show you where your tasks are located, how far away, and a route to get there. You can assign due date, due time, priority, and tags all on one screen.
- Advanced repeating options
- Projects with sub-tasks
- Shopping lists with check boxes - Iike this!
You can sync with Toodledo and share tasks by email or import.
See website for list of features. There are many more than I have listed here.
Awesome app for $4.99!
