Provided herein are new devices for indicating the status of events, such as the number of relevant events that are remaining and/or that have already occurred up to the present moment and to related devices, systems, and methods. In some aspects, the event-related indicator devices of the invention are used within larger dispensing devices or systems, e.g., to provide the status of administration of a substance contained therein (e.g., a drug). In an exemplary embodiment, the indicator devices find particular utility within medicament dispensers, such as metered dose inhalers, to provide a visual indication of the status of doses having been or remaining to be administered.
