Vito Technology released a new application for the iPhone called Task2Gather.
A task manager, Task2Gather allows users to create and store tasks in the iPhone application and then share those tasks online. According to the company, every single task can be divided into several sub-tasks, and these sub-tasks can be divided further without limit.
Since the tasks are stored on the Web, people that have access to your tasks can update the information and it will be changed on your iPhone.
Task2Gather costs $4.99 and is available on the App Store.
