I have just published a new app for Windows Phone called QuickDo.
Here is the description of what it does:
Simply the fastest app for ToodleDo.com. Guaranteed, or your money back! QuickDo lets you do two things … fast! Add a task to your ToodleDo.com task list and View your current tasks. It even lets you pin a tile to the start screen that lets you quickly access your current task list! Nothing more, nothing less.
