You can set an alarm to ring every day at a specific time or only once and choose which ring tone it should alert you with. While the alarm clock doesn't work if your iPhone is completely switched off, it will still function if your iPhone is locked.
The iOS 10 alarm clock will turn off after 15 minutes and there's nothing you can do about it, it's built that way. Even if you turn off Snooze, it will still stop.
The next time you hear an alarm going off on a family member's iPhone and your own iPhone or iPad is within earshot, simply say "Hey Siri, turn off the alarm on Anna's iPhone" (or the name of whoever's iPhone it's likely to be).

All you have to do use a "Hey Siri" voice command on your iPhone and ask it to turn off the alarm from [the person's name] iPhone. Siri will then ask you to confirm that you want to stop the alarm, and then you simply respond "Yes." Alternately, you can select the "yes" option that pops up on your iPhone.
Some alarm clocks can be turned back on if someone shuts them off. Some will repeat it on then off, but will stop after a certain amount of times. The most common alarm clock will stay on for an hour.
Most Androids will let you change the duration to 1 minute, 5 minutes, 15 minutes, 20 minutes, 25 minutes, or never. If you set your alarm to never, the alarm will keep ringing until it runs out of battery - so be warned if you're prone to leaving your phone unattended somewhere!
