“Zero-click” viewing of sensor data without any user input is provided. A display with sensor data may be “always on,” and may enable discrete viewing of sensor data without significant user hassle. Also, a system may be configured to display only current data, and/or to display the most current data for only a set interval. Also, one device in a continuous analyte monitoring system may be designated as a primary device, or hub, for receiving sensor data, and may control the flow of information and/or alerts to other devices in the system. Sensor data and/or alerts may be sent to a hierarchy of devices and/or persons in a designated order.
