Abstract: A one-touch portable handheld time keeping and recording device displays a list of tasks, the time elapsed and the status for each task on a handheld device with a touch-sensitive display. The user indicates the start or end of a task by touching the task or by clicking on it. If the task is active, the timer for that task is stopped and the task duration is stored. If the task is not active, the timer for that task is activated and any active timer is stopped. The task durations are updated in real-time or periodically. The time information from the one-touch portable handheld time keeping and recording device can be synchronized with a PC and pulled to a central repository where is can be maintained and billed.
