Mobile App alerts

Mobile App needs to be able to automatically send a message to staff if something on their rota/schedule has changed. E.g. visits added, amended, deleted. Also when there has been information added to the record of a client they are due to visit e.g. now needs to take X drug in the morning. At the moment, after we have made the change we then have to also duplicate the information in a text or email to the staff member.
