A method comprising: at an electronic device: receiving a first information representing a first time-based notification condition; setting a first time-based notification based on the first time-based notification condition; and in response to a determination that the first time-based notification condition has occurred: in accordance with a determination that the electronic device is not currently causing output of an audio notification based on at least one time-based notification other than the first time-based notification, causing output of a first audio notification; and in accordance with a determination that the electronic device is currently causing output of the audio notification based on at least one time-based notification other than the first time-based notification; causing output of a second audio notification audibly different from the first audio notification, wherein the at least one time-based notification other than the first time-based notification is a second time based notification, and wherein the second time-based notification was previously set by the electronic device based on a second time-based notification condition; and while causing output of the second audio notification and while the first time-based notification and the second time-based notification have not been dismissed: causing output of audio identifiers that identify the first time-based notification and the second time-based notification, wherein the respective audio identifiers are different from the first audio notification and the second audio notification. receiving a first information representing a first time-based notification condition; setting a first time-based notification based on the first time-based notification condition; and in response to a determination that the first time-based notification condition has occurred: in accordance with a determination that the electronic device is not currently causing output of an audio notification based on at least one time-based notification other than the first time-based notification, causing output of a first audio notification; and in accordance with a determination that the electronic device is currently causing output of the audio notification based on at least one time-based notification other than the first time-based notification; causing output of a second audio notification audibly different from the first audio notification, wherein the at least one time-based notification other than the first time-based notification is a second time based notification, and wherein the second time-based notification was previously set by the electronic device based on a second time-based notification condition; and while causing output of the second audio notification and while the first time-based notification and the second time-based notification have not been dismissed: causing output of audio identifiers that identify the first time-based notification and the second time-based notification, wherein the respective audio identifiers are different from the first audio notification and the second audio notification. in accordance with a determination that the electronic device is not currently causing output of an audio notification based on at least one time-based notification other than the first time-based notification, causing output of a first audio notification; and in accordance with a determination that the electronic device is currently causing output of the audio notification based on at least one time-based notification other than the first time-based notification; causing output of a second audio notification audibly different from the first audio notification, wherein the at least one time-based notification other than the first time-based notification is a second time based notification, and wherein the second time-based notification was previously set by the electronic device based on a second time-based notification condition; and while causing output of the second audio notification and while the first time-based notification and the second time-based notification have not been dismissed: causing output of audio identifiers that identify the first time-based notification and the second time-based notification, wherein the respective audio identifiers are different from the first audio notification and the second audio notification.
