SmartCall is a smartphone application that allows users to define profiles for different activities that specify which important contacts can reach them and for what purposes. The profiles include a white list of contacts and define how the user will be notified of calls from those contacts, such as with a special ringtone or callback button. It also lets white listed contacts request a callback if the user has SmartCall enabled by providing a reason for the call to bypass mute mode. The app is available across iOS, Android, and Windows platforms.
