Sure, I could tell Siri to disable all my alarms; but it rarely works correctly and I also need to tell her to remind me later to enable them. But the new Shortcuts app is amazing for this. Now, I just swipe to my widgets and tap my new Disable Alarms button. It turns off all my alarms and sets a reminder for 3:30pm to "Enable Alarms." Then when I get that reminder, all I have to do is go to my Enable Alarms shortcut and tap it. I've also added these shortcuts to Siri. So now when I say "disable school alarms" it will run the shortcut (including the reminder).
