Things is a beautifully focused and amazingly intuitive task manager. Other to-do applications either oversimplify or are too difficult to use. Either way you are not getting stuff done. Things instead has the right balance between ease of use and powerful features.

With Things' elegance and beautiful design, procrastinating never looked less attractive. You can even sync wirelessly with the desktop version of Things using Wi-Fi.

This is just what I'm looking for! I can organize both working and personal projects. WoW
