The Rock, of all people, created an alarm clock app. The professional wrestler and movie star will tell you to wake up 25 different ways, and can help remind you of important things. He can also send pre-recorded video messages to you. The Rock is known for his nonstop work ethic, so the lack of a snooze button in the app isn't an oversight or a bug -- it's a feature. You can download the app for free from Google Play.
