LIST1112 is a task management tool with multi-device authentication which can accept sign-in on one account from different hand-held devices.
You can input your tasks and the syncing among devices happens automatically anywhere with a network.
Its clean, crisp interface is aimed to avoid eye strain and let all your tasks stay organized on your hand.
You may also need sometimes to list down your ideas onto a sheet of paper, whether away from the devices or you would like to let them stay in a highly visible area. So, a printable version of your list is also available for printing out a single list at a time in order to guarantee your management of the tasks everywhere.
