When turned ON it will sound a loud annoying siren when the phone is unplugged from its charger, until the alarm is turned off. When enabled and minimized, an alert is shown as a reminder that the alarm is on.
The alarm must be turned on to be used. It does not stay on all the time, so feel free to plug and unplug as normal and only activate when needed.
Recently changed in this version:
Made more reliable.
Moved the plug monitoring to a service. The monitor should not close when minimized, moved to the back, or when other apps are run.
Removed unnecessary permission for battery info.
