A computer implemented method, apparatus, and computer usable program code to generate proximity-based task alerts in a mobile computing device. A geographic location is linked to a set of tasks in a task list. A user selects a proximity to the geographic location for the alarm to form a selected proximity. A determination is made as to whether the mobile computing device is within the selected proximity. A proximity task-reminder alarm is triggered in response to making a determination that the mobile computing device is within the selected proximity.
