Can I make an alarm hard to dismiss?

Yes. If you turn your alarm off in your sleep, an alarm that asks something of you first is the fix.

When editing an alarm you can require one of:

• Hold — press and hold, long enough that it cannot be done half asleep.
• Phrase — type out a phrase you have set.
• Maths — solve a problem.
• Barcode — scan a specific barcode, so you have to walk to the kitchen.
• Photo — take a picture of a particular place, so you have to get up and go there.

The barcode and photo challenges are the ones that actually get people out of bed, because they cannot be completed from under the duvet.
