A lot of people like to (or at least used to like to, before they started using smart phones as alarm clocks instead of good old clock radios) wake up to a local news station to hear traffic, weather, sports scores and more, or to their favorite music station. Since your iPhone is capable of tuning into just about any radio station you'd think there would be an option to have the alarm automatically tune to one of your choice.
Bedtime is a beautifully designed new feature of the Clock app meant to help you keep and monitor your sleep schedule. The best aspect of it, besides its simplicity, is that it has an independent volume setting and an array of wakeup sounds with soothing melodies that gradually get louder, easing you out of sleep rather than shocking your system with a harsh alarm. When you use it for the first time you simply tell it when you get up and how many hours you like to sleep, then you can select which days of the week you want it applied to.
Putting your phone down at night can be a hard thing to do, especially if you are constantly bombarded with messages, emails and other notifications. While Do Not Disturb silences notifications, you will still see them pop up if you are using your iPhone for something else like reading an e-book or a web page before closing your eyes for the night, and sometimes all it takes is one pesky notification to send you down a rabbit hole for the next half hour or so. iOS 12 introduces a Bedtime Mode for Do Not Disturb that will block notifications from showing while you are using your iPhone.
