Ticki is a front end to the Google Tasks todo-list. Ticki exposes all functionality from the Google Tasks interface: create, update and delete lists and tasks, and manage order of the tasks and the task hierarchy. All this through a intuitive user interface superior to that of the web-based interfaces at GMail and Google Calendar. It is both optimized for desktop use (keyboard and mouse) as well as touch devices such as tablets. Two different presentation modes are tailored for those distinct use cases.
