ColdBrew must be running, awake, and online to detect and send the low-battery event. A keep-awake session does not need to be active.

The Mac and iPhone apps are in development for a coordinated version 1.0 release. The browser alert is a simulation: no device is connected and no notification is sent. Phone quiet hours silence alert sounds; an active Mac quiet window also silences alerts sent then. Apple notification delivery can be delayed or missed.
