Devices and methods for prioritizing alert recipients using activity monitoring data are disclosed. A method includes: receiving, by a computing device, an incoming alert; receiving, by the computing device, activity data corresponding to a first on-call person; determining, by the computing device, whether or not the first on-call person is available using the activity data corresponding to the first on-call person; in response to determining that the first on-call person is available, the computing device sending the incoming alert to the first on-call person; and in response to determining that the first on-call person is not available, the computing device sending the incoming alert to a second on-call person.
