iOS 10 Bedtime feature sets an alarm for when to sleep – but might lead to problems waking up

The new Bedtime feature is a new kind of alarm – meant not only to be set for when you wake up, but also when you should be going to sleep. It aims to make sure that people spend enough time in bed by alerting them to their sleep time, and analysing whether or not they're actually making it into bed on time. It's used by heading to the Clock app in iOS 10, where there is a new tab at the bottom. There, you'll get the option to add what time you want to wake up and then what time you want to go to sleep. This might be the first thing you notice, and it's probably the most significant change to your daily routine.
