TodoWTF is a concept (as of now) rewarding todo list. The thought is that gamification with badges and points will motivate the user to complete tasks.

TodoWTF Sign Up Page
The user must first sign up to use the service. Each user has own account and sharing is not enabled. Social features may be implemented at some point.

TodoWTF Completed
This view shows completed tasks. A user can uncheck it and make it incomplete again. User can search for old tasks and they never get deleted.

TodoWTF Badges
The user is awarded badges based on tasks completed, created, point reward system, and more.

TodoWTF Points
The user earns points by getting badges, completing tasks, and creating tasks. Late tasks can lead to points being lost. The thought is that user can buy or purchase items with points.
