There is a number of different alarm clock apps available in the App Store. If you have trouble getting out of bed, you can ask Carrot to wake you up. If you prefer a lighter touch, Rise is a bit mellower.
Summarise – Talking Alarm Clock is an alarm clock that wakes you up with the news, a list of emails, your day's schedule, and more. In addition to showing you what is in store for you today, Summarise uses Siri's voice to read to you, too.
