Systems, methods, and software can be used to manage tasks on an electronic device. In some aspects, a computer-implemented method comprises: determining, by an electronic device, that a last calendar event associated with a task has been completed; in response to determining that the last calendar event has been completed, outputting, on the electronic device, a task user interface, wherein the task user interface comprises a task status field; receiving, through the task user interface, a user input indicating a task status value; and updating, by the electronic device, a task status based on the task status value.
