This has been bugging me for ages. I use Siri to set alarms all the time and pretty soon there's a gigantic list of scrolling alarms that need to be deleted one at a time with each delete being a two step process. There is no 'delete all alarms' command.
Then just for the hell of it I asked Siri to delete all alarms and wa la.
